    /**
      An `Ember.Binding` connects the properties of two objects so that whenever
      the value of one property changes, the other property will be changed also.
      ## Automatic Creation of Bindings with `/^*Binding/`-named Properties
      You do not usually create Binding objects directly but instead describe
      bindings in your class or object definition using automatic binding
      detection.
      Properties ending in a `Binding` suffix will be converted to `Ember.Binding`
      instances. The value of this property should be a string representing a path
      to another object or a custom binding instance created using Binding helpers
      (see "One Way Bindings"):
      ```
      valueBinding: "MyApp.someController.title"
      ```
      This will create a binding from `MyApp.someController.title` to the `value`
      property of your object instance automatically. Now the two values will be
      kept in sync.
      ## One Way Bindings
      One especially useful binding customization you can use is the `oneWay()`
      helper. This helper tells Ember that you are only interested in
      receiving changes on the object you are binding from. For example, if you
      are binding to a preference and you want to be notified if the preference
      has changed, but your object will not be changing the preference itself, you
      could do:
      ```
      bigTitlesBinding: Ember.Binding.oneWay("MyApp.preferencesController.bigTitles")
      ```
      This way if the value of `MyApp.preferencesController.bigTitles` changes the
      `bigTitles` property of your object will change also. However, if you
      change the value of your `bigTitles` property, it will not update the
      `preferencesController`.
      One way bindings are almost twice as fast to setup and twice as fast to
      execute because the binding only has to worry about changes to one side.
      You should consider using one way bindings anytime you have an object that
      may be created frequently and you do not intend to change a property; only
      to monitor it for changes (such as in the example above).
      ## Adding Bindings Manually
      All of the examples above show you how to configure a custom binding, but the
      result of these customizations will be a binding template, not a fully active
      Binding instance. The binding will actually become active only when you
      instantiate the object the binding belongs to. It is useful however, to
      understand what actually happens when the binding is activated.
      For a binding to function it must have at least a `from` property and a `to`
      property. The `from` property path points to the object/key that you want to
      bind from while the `to` path points to the object/key you want to bind to.
      When you define a custom binding, you are usually describing the property
      you want to bind from (such as `MyApp.someController.value` in the examples
      above). When your object is created, it will automatically assign the value
      you want to bind `to` based on the name of your binding key. In the
      examples above, during init, Ember objects will effectively call
      something like this on your binding:
      ```javascript
      binding = Ember.Binding.from("valueBinding").to("value");
      ```
      This creates a new binding instance based on the template you provide, and
      sets the to path to the `value` property of the new object. Now that the
      binding is fully configured with a `from` and a `to`, it simply needs to be
      connected to become active. This is done through the `connect()` method:
      ```javascript
      binding.connect(this);
      ```
      Note that when you connect a binding you pass the object you want it to be
      connected to. This object will be used as the root for both the from and
      to side of the binding when inspecting relative paths. This allows the
      binding to be automatically inherited by subclassed objects as well.
      This also allows you to bind between objects using the paths you declare in
      `from` and `to`:
      ```javascript
      // Example 1
      binding = Ember.Binding.from("App.someObject.value").to("value");
      binding.connect(this);
      // Example 2
      binding = Ember.Binding.from("parentView.value").to("App.someObject.value");
      binding.connect(this);
      ```
      Now that the binding is connected, it will observe both the from and to side
      and relay changes.
      If you ever needed to do so (you almost never will, but it is useful to
      understand this anyway), you could manually create an active binding by
      using the `Ember.bind()` helper method. (This is the same method used by
      to setup your bindings on objects):
      ```javascript
      Ember.bind(MyApp.anotherObject, "value", "MyApp.someController.value");
      ```
      Both of these code fragments have the same effect as doing the most friendly
      form of binding creation like so:
      ```javascript
      MyApp.anotherObject = Ember.Object.create({
        valueBinding: "MyApp.someController.value",
        // OTHER CODE FOR THIS OBJECT...
      });
      ```
      Ember's built in binding creation method makes it easy to automatically
      create bindings for you. You should always use the highest-level APIs
      available, even if you understand how it works underneath.

    /**
      A computed property transforms an objects function into a property.
      By default the function backing the computed property will only be called
      once and the result will be cached. You can specify various properties
      that your computed property is dependent on. This will force the cached
      result to be recomputed if the dependencies are modified.
      In the following example we declare a computed property (by calling
      `.property()` on the fullName function) and setup the properties
      dependencies (depending on firstName and lastName). The fullName function
      will be called once (regardless of how many times it is accessed) as long
      as it's dependencies have not been changed. Once firstName or lastName are updated
      any future calls (or anything bound) to fullName will incorporate the new
      values.
      ```javascript
      var Person = Ember.Object.extend({
        // these will be supplied by `create`
        firstName: null,
        lastName: null,
        fullName: function() {
          var firstName = this.get('firstName');
          var lastName = this.get('lastName');
         return firstName + ' ' + lastName;
        }.property('firstName', 'lastName')
      });
      var tom = Person.create({
        firstName: 'Tom',
        lastName: 'Dale'
      });
      tom.get('fullName') // 'Tom Dale'
      ```
      You can also define what Ember should do when setting a computed property.
      If you try to set a computed property, it will be invoked with the key and
      value you want to set it to. You can also accept the previous value as the
      third parameter.
      ```javascript
      var Person = Ember.Object.extend({
        // these will be supplied by `create`
        firstName: null,
        lastName: null,
        fullName: function(key, value, oldValue) {
          // getter
          if (arguments.length === 1) {
            var firstName = this.get('firstName');
            var lastName = this.get('lastName');
            return firstName + ' ' + lastName;
          // setter
          } else {
            var name = value.split(' ');
            this.set('firstName', name[0]);
            this.set('lastName', name[1]);

      person.set('fullName', 'Peter Wagenet');
      person.get('firstName'); // 'Peter'

      This helper returns a new property descriptor that wraps the passed
      computed property function. You can use this helper to define properties
      with mixins or via `Ember.defineProperty()`.
      The function you pass will be used to both get and set property values.
      The function should accept two parameters, key and value. If value is not
      undefined you should set the value first. In either case return the
      current value of the property.
      
      A computed property defined in this way might look like this:
      ```js
      var Person = Ember.Object.extend({
        firstName: 'Betty',
        lastName: 'Jones',
        fullName: Ember.computed('firstName', 'lastName', function(key, value) {
          return this.get('firstName') + ' ' + this.get('lastName');
        })
      });
      var client = Person.create();
      client.get('fullName'); // 'Betty Jones'
      
      client.set('lastName', 'Fuller');
      client.get('fullName'); // 'Betty Fuller'
      ```
      _Note: This is the prefered way to define computed properties when writing third-party
      libraries that depend on or use Ember, since there is no guarantee that the user
      will have prototype extensions enabled._
      You might use this method if you disabled
      [Prototype Extensions](http://emberjs.com/guides/configuring-ember/disabling-prototype-extensions/).
      The alternative syntax might look like this
      (if prototype extensions are enabled, which is the default behavior):
      ```js
      fullName: function () {
        return this.get('firstName') + ' ' + this.get('lastName');
      }.property('firstName', 'lastName')

      The purpose of the Ember Instrumentation module is
      to provide efficient, general-purpose instrumentation
      for Ember.
      Subscribe to a listener by using `Ember.subscribe`:
      ```javascript
      Ember.subscribe("render", {
        before: function(name, timestamp, payload) {
        },
        after: function(name, timestamp, payload) {
        }
      });
      ```
      If you return a value from the `before` callback, that same
      value will be passed as a fourth parameter to the `after`
      callback.
      Instrument a block of code by using `Ember.instrument`:
      ```javascript
      Ember.instrument("render.handlebars", payload, function() {
        // rendering logic
      }, binding);
      ```
      Event names passed to `Ember.instrument` are namespaced
      by periods, from more general to more specific. Subscribers
      can listen for events by whatever level of granularity they
      are interested in.
      In the above example, the event is `render.handlebars`,
      and the subscriber listened for all events beginning with
      `render`. It would receive callbacks for events named
      `render`, `render.handlebars`, `render.container`, or
      even `render.handlebars.layout`.

      JavaScript (before ES6) does not have a Map implementation. Objects,

      Because Ember has a way to get a unique identifier for every object
      via `Ember.guidFor`, we can implement a performant Map with arbitrary
      keys. Because it is commonly used in low-level bookkeeping, Map is
      implemented as a pure JavaScript object for performance.
      This implementation follows the current iteration of the ES6 proposal for
      maps (http://wiki.ecmascript.org/doku.php?id=harmony:simple_maps_and_sets),
      with two exceptions. First, because we need our implementation to be pleasant
      on older browsers, we do not use the `delete` name (using `remove` instead).
      Second, as we do not have the luxury of in-VM iteration, we implement a
      forEach method for iteration.
      Map is mocked out to look like an Ember object, so you can do
      `Ember.Map.create()` for symmetry with other Ember classes.

      The `Ember.Mixin` class allows you to create mixins, whose properties can be
      added to other classes. For instance,
      ```javascript
      App.Editable = Ember.Mixin.create({
        edit: function() {
          console.log('starting to edit');
          this.set('isEditing', true);

      });
      // Mix mixins into classes by passing them as the first arguments to
      // .extend.
      App.CommentView = Ember.View.extend(App.Editable, {
        template: Ember.Handlebars.compile('{{#if view.isEditing}}...{{else}}...{{/if}}')
      });
      commentView = App.CommentView.create();
      commentView.edit(); // outputs 'starting to edit'
      ```
      Note that Mixins are created with `Ember.Mixin.create`, not
      `Ember.Mixin.extend`.
      Note that mixins extend a constructor's prototype so arrays and object literals
      defined as properties will be shared amongst objects that implement the mixin.
      If you want to define a property in a mixin that is not shared, you can define
      it either as a computed property or have it be created on initialization of the object.
      ```javascript
      //filters array will be shared amongst any object implementing mixin
      App.Filterable = Ember.Mixin.create({
        filters: Ember.A()
      });
      //filters will be a separate  array for every object implementing the mixin
      App.Filterable = Ember.Mixin.create({
        filters: Ember.computed(function(){return Ember.A();})
      });
      //filters will be created as a separate array during the object's initialization
      App.Filterable = Ember.Mixin.create({

      NOTE: This is a low-level method used by other parts of the API. You almost
      never want to call this method directly. Instead you should use
      `Ember.mixin()` to define new properties.
      Defines a property on an object. This method works much like the ES5
      `Object.defineProperty()` method except that it can also accept computed
      properties and other special descriptors.
      Normally this method takes only three parameters. However if you pass an
      instance of `Ember.Descriptor` as the third param then you can pass an
      optional value as the fourth parameter. This is often more efficient than
      creating new descriptor hashes for each property.
      ## Examples
      ```javascript
      // ES5 compatible mode
      Ember.defineProperty(contact, 'firstName', {
        writable: true,
        configurable: false,
        enumerable: true,
        value: 'Charles'
      });
      // define a simple property
      Ember.defineProperty(contact, 'lastName', undefined, 'Jolley');
      // define a computed property
      Ember.defineProperty(contact, 'fullName', Ember.computed(function() {
        return this.firstName+' '+this.lastName;
      }).property('firstName', 'lastName'));
      ```

      @param {String} keyName the name of the property
      @param {Ember.Descriptor} [desc] an instance of `Ember.Descriptor` (typically a
        computed property) or an ES5 descriptor.
        You must provide this or `data` but not both.

      Provides a useful utility for when integrating with non-Ember libraries
      that provide asynchronous callbacks.
      Ember utilizes a run-loop to batch and coalesce changes. This works by
      marking the start and end of Ember-related Javascript execution.
      When using events such as a View's click handler, Ember wraps the event
      handler in a run-loop, but when integrating with non-Ember libraries this
      can be tedious.
      For example, the following is rather verbose but is the correct way to combine
      third-party events and Ember code.
      ```javascript
      var that = this;
      jQuery(window).on('resize', function(){
        run(function(){
          that.handleResize();
        });
      });
      ```
      To reduce the boilerplate, the following can be used to construct a
      run-loop-wrapped callback handler.
      ```javascript
      jQuery(window).on('resize', run.bind(this, this.handleResize));

      ```
      Multiple operations scheduled with `run.next` will coalesce
      into the same later run loop, along with any other operations
      scheduled by `run.later` that expire right around the same
      time that `run.next` operations will fire.
      Note that there are often alternatives to using `run.next`.
      For instance, if you'd like to schedule an operation to happen
      after all DOM element operations have completed within the current
      run loop, you can make use of the `afterRender` run loop queue (added
      by the `ember-views` package, along with the preceding `render` queue
      where all the DOM element operations happen). Example:
      ```javascript
      App.MyCollectionView = Ember.CollectionView.extend({
        didInsertElement: function() {
          run.scheduleOnce('afterRender', this, 'processChildElements');
        },
        processChildElements: function() {
          // ... do something with collectionView's child view
          // elements after they've finished rendering, which
          // can't be done within the CollectionView's
          // `didInsertElement` hook because that gets run
          // before the child elements have been added to the DOM.
        }
      });

      One benefit of the above approach compared to using `run.next` is
      that you will be able to perform DOM/CSS operations before unprocessed
      elements are rendered to the screen, which may prevent flickering or
      other artifacts caused by delaying processing until after rendering.
      The other major benefit to the above approach is that `run.next`
      introduces an element of non-determinism, which can make things much
      harder to test, due to its reliance on `setTimeout`; it's much harder
      to guarantee the order of scheduled operations when they are scheduled
      outside of the current run loop, i.e. with `run.next`.

      Strongly hint runtimes to intern the provided string.
      When do I need to use this function?
      For the most part, never. Pre-mature optimization is bad, and often the
      runtime does exactly what you need it to, and more often the trade-off isn't
      worth it.
      Why?
      Runtimes store strings in at least 2 different representations:
      Ropes and Symbols (interned strings). The Rope provides a memory efficient
      data-structure for strings created from concatenation or some other string
      manipulation like splitting.
      Unfortunately checking equality of different ropes can be quite costly as
      runtimes must resort to clever string comparison algorithims. These
      algorithims typically cost in proportion to the length of the string.
      Luckily, this is where the Symbols (interned strings) shine. As Symbols are
      unique by their string content, equality checks can be done by pointer
      comparision.
      How do I know if my string is a rope or symbol?
      Typically (warning general sweeping statement, but truthy in runtimes at
      present) static strings created as part of the JS source are interned.
      Strings often used for comparisions can be interned at runtime if some
      criteria are met.  One of these criteria can be the size of the entire rope.
      For example, in chrome 38 a rope longer then 12 characters will not
      intern, nor will segments of that rope.

      @deprecated
      @private
      In order to store defaults for a class, a prototype may need to create
      a default meta object, which will be inherited by any objects instantiated
      from the class's constructor.
      However, the properties of that meta object are only shallow-cloned,
      so if a property is a hash (like the event system's `listeners` hash),
      it will by default be shared across all instances of that class.
      This method allows extensions to deeply clone a series of nested hashes or
      other complex objects. For instance, the event system might pass
      `['listeners', 'foo:change', 'ember157']` to `prepareMetaPath`, which will
      walk down the keys provided.
      For each key, if the key does not exist, it is created. If it already
      exists and it was inherited from its constructor, the constructor's
      key is cloned.
      You can also pass false for `writable`, which will simply return
      undefined if `prepareMetaPath` discovers any part of the path that
      shared or undefined.

      removed from the dependent array(s) an array computed only operates
      on the change instead of re-evaluating the entire array. This should
      return an array, if you'd like to use "one at a time" semantics and
      compute some value other then an array look at
      `Ember.reduceComputed`.
      If there are more than one arguments the first arguments are
      considered to be dependent property keys. The last argument is
      required to be an options object. The options object can have the
      following three properties.
      `initialize` - An optional initialize function. Typically this will be used
      to set up state on the instanceMeta object.
      `removedItem` - A function that is called each time an element is
      removed from the array.
      `addedItem` - A function that is called each time an element is
      added to the array.
      The `initialize` function has the following signature:
      ```javascript
      function(array, changeMeta, instanceMeta)
      ```
      `array` - The initial value of the arrayComputed, an empty array.
      `changeMeta` - An object which contains meta information about the
      computed. It contains the following properties:
         - `property` the computed property
         - `propertyName` the name of the property on the object
      `instanceMeta` - An object that can be used to store meta
      information needed for calculating your computed. For example a
      unique computed might use this to store the number of times a given
      element is found in the dependent array.
      The `removedItem` and `addedItem` functions both have the following signature:
      ```javascript
      function(accumulatedValue, item, changeMeta, instanceMeta)
      ```
      `accumulatedValue` - The value returned from the last time
      `removedItem` or `addedItem` was called or an empty array.
      `item` - the element added or removed from the array
      `changeMeta` - An object which contains meta information about the
      change. It contains the following properties:
        - `property` the computed property
        - `propertyName` the name of the property on the object
        - `index` the index of the added or removed item
        - `item` the added or removed item: this is exactly the same as
          the second arg
        - `arrayChanged` the array that triggered the change. Can be
          useful when depending on multiple arrays.
      For property changes triggered on an item property change (when
      depKey is something like `someArray.@each.someProperty`),
      `changeMeta` will also contain the following property:
        - `previousValues` an object whose keys are the properties that changed on
        the item, and whose values are the item's previous values.
      `previousValues` is important Ember coalesces item property changes via
      Ember.run.once. This means that by the time removedItem gets called, item has
      the new values, but you may need the previous value (eg for sorting &
      filtering).
      `instanceMeta` - An object that can be used to store meta
      information needed for calculating your computed. For example a
      unique computed might use this to store the number of times a given
      element is found in the dependent array.
      The `removedItem` and `addedItem` functions should return the accumulated
      value. It is acceptable to not return anything (ie return undefined)
      to invalidate the computation. This is generally not a good idea for
      arrayComputed but it's used in eg max and min.
      Example
      ```javascript
      Ember.computed.map = function(dependentKey, callback) {
        var options = {
          addedItem: function(array, item, changeMeta, instanceMeta) {
            var mapped = callback(item);
            array.insertAt(changeMeta.index, mapped);
            return array;
          },
          removedItem: function(array, item, changeMeta, instanceMeta) {
            array.removeAt(changeMeta.index, 1);
            return array;
          }
        };
        return Ember.arrayComputed(dependentKey, options);
      };
      ```

    /**
      Creates a computed property which operates on dependent arrays and
      is updated with "one at a time" semantics. When items are added or
      removed from the dependent array(s) a reduce computed only operates
      on the change instead of re-evaluating the entire array.
      If there are more than one arguments the first arguments are
      considered to be dependent property keys. The last argument is
      required to be an options object. The options object can have the
      following four properties:
      `initialValue` - A value or function that will be used as the initial
      value for the computed. If this property is a function the result of calling
      the function will be used as the initial value. This property is required.
      `initialize` - An optional initialize function. Typically this will be used
      to set up state on the instanceMeta object.
      `removedItem` - A function that is called each time an element is removed
      from the array.
      `addedItem` - A function that is called each time an element is added to
      the array.
      The `initialize` function has the following signature:
      ```javascript
      function(initialValue, changeMeta, instanceMeta)
      ```
      `initialValue` - The value of the `initialValue` property from the
      options object.
      `changeMeta` - An object which contains meta information about the
      computed. It contains the following properties:
         - `property` the computed property
         - `propertyName` the name of the property on the object
      `instanceMeta` - An object that can be used to store meta
      information needed for calculating your computed. For example a
      unique computed might use this to store the number of times a given
      element is found in the dependent array.
      The `removedItem` and `addedItem` functions both have the following signature:
      ```javascript
      function(accumulatedValue, item, changeMeta, instanceMeta)
      ```
      `accumulatedValue` - The value returned from the last time
      `removedItem` or `addedItem` was called or `initialValue`.
      `item` - the element added or removed from the array
      `changeMeta` - An object which contains meta information about the
      change. It contains the following properties:
        - `property` the computed property
        - `propertyName` the name of the property on the object
        - `index` the index of the added or removed item
        - `item` the added or removed item: this is exactly the same as
          the second arg
        - `arrayChanged` the array that triggered the change. Can be
          useful when depending on multiple arrays.
      For property changes triggered on an item property change (when
      depKey is something like `someArray.@each.someProperty`),
      `changeMeta` will also contain the following property:
        - `previousValues` an object whose keys are the properties that changed on
        the item, and whose values are the item's previous values.
      `previousValues` is important Ember coalesces item property changes via
      Ember.run.once. This means that by the time removedItem gets called, item has
      the new values, but you may need the previous value (eg for sorting &
      filtering).
      `instanceMeta` - An object that can be used to store meta
      information needed for calculating your computed. For example a
      unique computed might use this to store the number of times a given
      element is found in the dependent array.
      The `removedItem` and `addedItem` functions should return the accumulated
      value. It is acceptable to not return anything (ie return undefined)
      to invalidate the computation. This is generally not a good idea for
      arrayComputed but it's used in eg max and min.
      Note that observers will be fired if either of these functions return a value
      that differs from the accumulated value.  When returning an object that
      mutates in response to array changes, for example an array that maps
      everything from some other array (see `Ember.computed.map`), it is usually
      important that the *same* array be returned to avoid accidentally triggering observers.
      Example
      ```javascript
      Ember.computed.max = function(dependentKey) {
        return Ember.reduceComputed(dependentKey, {
          initialValue: -Infinity,
          addedItem: function(accumulatedValue, item, changeMeta, instanceMeta) {
            return Math.max(accumulatedValue, item);
          },
          removedItem: function(accumulatedValue, item, changeMeta, instanceMeta) {
            if (item < accumulatedValue) {
              return accumulatedValue;
            }
          }
        });
      };
      ```
      Dependent keys may refer to `@this` to observe changes to the object itself,
      which must be array-like, rather than a property of the object.  This is
      mostly useful for array proxies, to ensure objects are retrieved via
      `objectAtContent`.  This is how you could sort items by properties defined on an item controller.
      Example
      ```javascript
      App.PeopleController = Ember.ArrayController.extend({
        itemController: 'person',
        sortedPeople: Ember.computed.sort('@this.@each.reversedName', function(personA, personB) {
          // `reversedName` isn't defined on Person, but we have access to it via
          // the item controller App.PersonController.  If we'd used
          // `content.@each.reversedName` above, we would be getting the objects
          // directly and not have access to `reversedName`.
          //
          var reversedNameA = get(personA, 'reversedName');
          var reversedNameB = get(personB, 'reversedName');
          return Ember.compare(reversedNameA, reversedNameB);
        })
      });
      App.PersonController = Ember.ObjectController.extend({
        reversedName: function() {
          return reverse(get(this, 'name'));
        }.property('name')
      });
      ```
      Dependent keys whose values are not arrays are treated as regular
      dependencies: when they change, the computed property is completely
      recalculated.  It is sometimes useful to have dependent arrays with similar
      semantics.  Dependent keys which end in `.[]` do not use "one at a time"
      semantics.  When an item is added or removed from such a dependency, the
      computed property is completely recomputed.
      When the computed property is completely recomputed, the `accumulatedValue`
      is discarded, it starts with `initialValue` again, and each item is passed
      to `addedItem` in turn.
      Example
      ```javascript
      Ember.Object.extend({
        // When `string` is changed, `computed` is completely recomputed.
        string: 'a string',
        // When an item is added to `array`, `addedItem` is called.
        array: [],
        // When an item is added to `anotherArray`, `computed` is completely
        // recomputed.
        anotherArray: [],
        computed: Ember.reduceComputed('string', 'array', 'anotherArray.[]', {
          addedItem: addedItemCallback,
          removedItem: removedItemCallback
        })
      });
      ```

      A computed property which returns a new array with all the

      or sort function.
      The callback method you provide should have the following signature:
      ```javascript
      function(itemA, itemB);
      ```
      - `itemA` the first item to compare.
      - `itemB` the second item to compare.
      This function should return negative number (e.g. `-1`) when `itemA` should come before
      `itemB`. It should return positive number (e.g. `1`) when `itemA` should come after
      `itemB`. If the `itemA` and `itemB` are equal this function should return `0`.
      Therefore, if this function is comparing some numeric values, simple `itemA - itemB` or
      `itemA.get( 'foo' ) - itemB.get( 'foo' )` can be used instead of series of `if`.

    /**
      `Ember.ArrayController` provides a way for you to publish a collection of
      objects so that you can easily bind to the collection from a Handlebars
      `#each` helper, an `Ember.CollectionView`, or other controllers.
      The advantage of using an `ArrayController` is that you only have to set up
      your view bindings once; to change what's displayed, simply swap out the
      `model` property on the controller.
      For example, imagine you wanted to display a list of items fetched via an XHR
      request. Create an `Ember.ArrayController` and set its `model` property:
      ```javascript
      MyApp.listController = Ember.ArrayController.create();
      $.get('people.json', function(data) {
        MyApp.listController.set('model', data);
      });
      ```
      Then, create a view that binds to your new controller:
      ```handlebars
      {{#each MyApp.listController}}
        {{firstName}} {{lastName}}
      {{/each}}
      ```
      Although you are binding to the controller, the behavior of this controller
      is to pass through any methods or properties to the underlying array. This
      capability comes from `Ember.ArrayProxy`, which this class inherits from.
      Sometimes you want to display computed properties within the body of an
      `#each` helper that depend on the underlying items in `model`, but are not
      present on those items.   To do this, set `itemController` to the name of a
      controller (probably an `ObjectController`) that will wrap each individual item.
      For example:
      ```handlebars
      {{#each post in controller}}
        <li>{{post.title}} ({{post.titleLength}} characters)</li>
      {{/each}}
      ```
      ```javascript
      App.PostsController = Ember.ArrayController.extend({
        itemController: 'post'
      });
      App.PostController = Ember.ObjectController.extend({
        // the `title` property will be proxied to the underlying post.
        titleLength: function() {
          return this.get('title').length;
        }.property('title')
      });
      ```
      In some cases it is helpful to return a different `itemController` depending
      on the particular item.  Subclasses can do this by overriding
      `lookupItemController`.
      For example:
      ```javascript
      App.MyArrayController = Ember.ArrayController.extend({
        lookupItemController: function( object ) {
          if (object.get('isSpecial')) {
            return "special"; // use App.SpecialController
          } else {
            return "regular"; // use App.RegularController
          }
        }
      });
      ```
      The itemController instances will have a `parentController` property set to
      the `ArrayController` instance.

        be used to lookup the container for the controller. As an alternative, you
        can also provide a controller class as the value.
        For example:
        ```javascript
        App.MyArrayController = Ember.ArrayController.extend({
          itemController: Ember.ObjectController.extend({

        Computed properties allow you to treat a function like a property:

        });
        var president = MyApp.President.create({
          firstName: 'Barack',
          lastName: 'Obama'
        });
        president.get('fullName'); // 'Barack Obama'
        ```
        Treating a function like a property is useful because they can work with
        bindings, just like any other property.
        Many computed properties have dependencies on other properties. For
        example, in the above example, the `fullName` property depends on
        `firstName` and `lastName` to determine its value. You can tell Ember
        about these dependencies like this:
        ```javascript
        MyApp.President = Ember.Object.extend({
          firstName: '',
          lastName:  '',
          fullName: function() {
            return this.get('firstName') + ' ' + this.get('lastName');
            // Tell Ember.js that this computed property depends on firstName
            // and lastName
          }.property('firstName', 'lastName')
        });
        ```
        Make sure you list these dependencies so Ember knows when to update
        bindings that connect to a computed property. Changing a dependency
        will not immediately trigger an update of the computed property, but
        will instead clear the cache so that it is updated when the next `get`
        is called on the property.
        See [Ember.ComputedProperty](/api/classes/Ember.ComputedProperty.html), [Ember.computed](/api/#method_computed).

      `Ember.ActionHandler` is available on some familiar classes including

      `Ember.Controller` and `Ember.ObjectController`.

      inheritance.)

        The collection of functions, keyed by name, available on this
        `ActionHandler` as action targets.
        These functions will be invoked when a matching `{{action}}` is triggered
        from within a template and the application's current route is this route.
        Actions can also be invoked from other parts of your application
        via `ActionHandler#send`.
        The `actions` hash will inherit action handlers from
        the `actions` hash defined on extended parent classes
        or mixins rather than just replace the entire hash, e.g.:
        ```js
        App.CanDisplayBanner = Ember.Mixin.create({
          actions: {
            displayBanner: function(msg) {
              // ...
            }
          }
        });
        App.WelcomeRoute = Ember.Route.extend(App.CanDisplayBanner, {
          actions: {
            playMusic: function() {
              // ...
            }
          }
        });
        // `WelcomeRoute`, when active, will be able to respond
        // to both actions, since the actions hash is merged rather
        // then replaced when extending mixins / parent classes.
        this.send('displayBanner');
        this.send('playMusic');
        ```
        Within a Controller, Route, View or Component's action handler,
        the value of the `this` context is the Controller, Route, View or
        Component object:
        ```js
        App.SongRoute = Ember.Route.extend({
          actions: {
            myAction: function() {
              this.controllerFor("song");
              this.transitionTo("other.route");
              ...
            }
          }
        });
        ```
        It is also possible to call `this._super()` from within an
        action handler if it overrides a handler defined on a parent
        class or mixin:
        Take for example the following routes:
        ```js
        App.DebugRoute = Ember.Mixin.create({
          actions: {
            debugRouteInformation: function() {
              console.debug("trololo");
            }
          }
        });
        App.AnnoyingDebugRoute = Ember.Route.extend(App.DebugRoute, {
          actions: {
            debugRouteInformation: function() {
              // also call the debugRouteInformation of mixed in App.DebugRoute
              this._super();
              // show additional annoyance
              window.alert(...);
            }
          }
        });
        ```
        ## Bubbling
        By default, an action will stop bubbling once a handler defined
        on the `actions` hash handles it. To continue bubbling the action,
        you must return `true` from the handler:
        ```js
        App.Router.map(function() {
          this.resource("album", function() {
            this.route("song");
          });
        });
        App.AlbumRoute = Ember.Route.extend({
          actions: {
            startPlaying: function() {
            }
          }
        });
        App.AlbumSongRoute = Ember.Route.extend({

      This mixin implements Observer-friendly Array-like behavior. It is not a
      concrete implementation, but it can be used up by other classes that want
      to appear like arrays.
      For example, ArrayProxy and ArrayController are both concrete classes that can
      be instantiated to implement array-like behavior. Both of these classes use
      the Array Mixin by way of the MutableArray mixin, which allows observable
      changes to be made to the underlying array.
      Unlike `Ember.Enumerable,` this mixin defines methods specifically for
      collections that provide index-ordered access to their contents. When you
      are designing code that needs to accept any kind of Array-like object, you
      should use these methods instead of Array primitives because these will
      properly notify observers of changes to the array.
      Although these methods are efficient, they do add a layer of indirection to
      your application so it is a good idea to use them only when you need the
      flexibility of using both true JavaScript arrays and "virtual" arrays such
      as controllers and collections.
      You can use the methods defined in this module to access and modify array
      contents in a KVO-friendly way. You can also be notified whenever the
      membership of an array changes by using `.observes('myArray.[]')`.
      To support `Ember.Array` in your own class, you must override two
      primitives to use it: `replace()` and `objectAt()`.
      Note that the Ember.Array mixin also incorporates the `Ember.Enumerable`
      mixin. All `Ember.Array`-like objects are also enumerable.

        If your object supports retrieving the value of an array item using `get()`
        (i.e. `myArray.get(0)`), then you do not need to implement this method
        yourself.

      This mixin defines the common interface implemented by enumerable objects
      in Ember. Most of these methods follow the standard Array iteration
      API defined up to JavaScript 1.8 (excluding language-specific features that
      cannot be emulated in older versions of JavaScript).
      This mixin is applied automatically to the Array class on page load, so you
      can use any of these methods on simple arrays. If Array already implements
      one of these methods, the mixin will not override them.
      ## Writing Your Own Enumerable
      To make your own custom class enumerable, you need two items:
      1. You must have a length property. This property should change whenever
         the number of items in your enumerable object changes. If you use this
         with an `Ember.Object` subclass, you should be sure to change the length
         property using `set().`
      2. You must implement `nextObject().` See documentation.
      Once you have these two methods implemented, apply the `Ember.Enumerable` mixin
      to your class and you will be able to enumerate the contents of your object
      like any other collection.
      ## Using Ember Enumeration with Other Libraries
      Many other libraries provide some kind of iterator or enumeration like
      facility. This is often where the most common API conflicts occur.
      Ember's API is designed to be as friendly as possible with other
      libraries by implementing only methods that mostly correspond to the
      JavaScript 1.8 API.
      @class Enumerable
      @namespace Ember

        Implement this method to make your class enumerable.
        This method will be call repeatedly during enumeration. The index value
        will always begin with 0 and increment monotonically. You don't have to
        rely on the index value to determine what object to return, but you should
        always check the value and start from the beginning when you see the
        requested index is 0.
        The `previousObject` is the object that was returned from the last call
        to `nextObject` for the current iteration. This is a useful way to
        manage iteration if you are tracing a linked list, for example.
        Finally the context parameter will always contain a hash you can use as
        a "scratchpad" to maintain any other state you need in order to iterate
        properly. The context object is reused and is not reset between
        iterations so make sure you setup the context with a fresh state whenever
        the index parameter is 0.
        Generally iterators will continue to call `nextObject` until the index
        reaches the your current length-1. If you run out of data before this
        time for some reason, you should simply return undefined.
        The default implementation of this method simply looks up the index.

      The `Ember.Freezable` mixin implements some basic methods for marking an
      object as frozen. Once an object is frozen it should be read only. No changes
      may be made the internal state of the object.
      ## Enforcement
      To fully support freezing in your subclass, you must include this mixin and
      override any method that might alter any property on the object to instead
      raise an exception. You can check the state of an object by checking the
      `isFrozen` property.
      Although future versions of JavaScript may support language-level freezing
      object objects, that is not the case today. Even if an object is freezable,
      it is still technically possible to modify the object, even though it could
      break other parts of your application that do not expect a frozen object to
      change. It is, therefore, very important that you always respect the
      `isFrozen` property on all freezable objects.
      ## Example Usage
      The example below shows a simple object that implement the `Ember.Freezable`
      protocol.
      ```javascript
      Contact = Ember.Object.extend(Ember.Freezable, {
        firstName: null,
        lastName: null,
        // swaps the names
        swapNames: function() {
          if (this.get('isFrozen')) throw Ember.FROZEN_ERROR;
          var tmp = this.get('firstName');
          this.set('firstName', this.get('lastName'));
          this.set('lastName', tmp);
          return this;
        }
      });
      c = Contact.create({ firstName: "John", lastName: "Doe" });
      c.swapNames();  // returns c
      c.freeze();
      c.swapNames();  // EXCEPTION
      ```
      ## Copying
      Usually the `Ember.Freezable` protocol is implemented in cooperation with the
      `Ember.Copyable` protocol, which defines a `frozenCopy()` method that will
      return a frozen object, if the object implements this method as well.
      @class Freezable
      @namespace Ember
      @since Ember 0.9

    /**
      ## Overview
      This mixin provides properties and property observing functionality, core
      features of the Ember object model.
      Properties and observers allow one object to observe changes to a
      property on another object. This is one of the fundamental ways that
      models, controllers and views communicate with each other in an Ember
      application.
      Any object that has this mixin applied can be used in observer
      operations. That includes `Ember.Object` and most objects you will
      interact with as you write your Ember application.
      Note that you will not generally apply this mixin to classes yourself,
      but you will use the features provided by this module frequently, so it
      is important to understand how to use it.
      ## Using `get()` and `set()`
      Because of Ember's support for bindings and observers, you will always
      access properties using the get method, and set properties using the
      set method. This allows the observing objects to be notified and
      computed properties to be handled properly.
      More documentation about `get` and `set` are below.
      ## Observing Property Changes
      You typically observe property changes simply by adding the `observes`
      call to the end of your method declarations in classes that you write.
      For example:
      ```javascript
      Ember.Object.extend({
        valueObserver: function() {
          // Executes whenever the "value" property changes
        }.observes('value')
      });
      ```
      Although this is the most common way to add an observer, this capability
      is actually built into the `Ember.Object` class on top of two methods
      defined in this mixin: `addObserver` and `removeObserver`. You can use
      these two methods to add and remove observers yourself if you need to
      do so at runtime.
      To add an observer for a property, call:
      ```javascript
      object.addObserver('propertyKey', targetObject, targetAction)
      ```
      This will call the `targetAction` method on the `targetObject` whenever
      the value of the `propertyKey` changes.
      Note that if `propertyKey` is a computed property, the observer will be
      called when any of the property dependencies are changed, even if the
      resulting value of the computed property is unchanged. This is necessary
      because computed properties are not computed until `get` is called.
      @class Observable
      @namespace Ember
    */
    __exports__["default"] = Mixin.create({
      /**
        Retrieves the value of a property from the object.
        This method is usually similar to using `object[keyName]` or `object.keyName`,
        however it supports both computed properties and the unknownProperty
        handler.
        Because `get` unifies the syntax for accessing all these kinds
        of properties, it can make many refactorings easier, such as replacing a
        simple property with a computed property, or vice versa.
        ### Computed Properties
        Computed properties are methods defined with the `property` modifier
        declared at the end, such as:
        ```javascript
        fullName: function() {
          return this.get('firstName') + ' ' + this.get('lastName');
        }.property('firstName', 'lastName')
        ```
        When you call `get` on a computed property, the function will be
        called and the return value will be returned instead of the function
        itself.
        ### Unknown Properties
        Likewise, if you try to call `get` on a property whose value is
        `undefined`, the `unknownProperty()` method will be called on the object.
        If this method returns any value other than `undefined`, it will be returned
        instead. This allows you to implement "virtual" properties that are
        not defined upfront.
        @method get
        @param {String} keyName The property to retrieve
        @return {Object} The property value or undefined.
      */
      get: function(keyName) {
        return get(this, keyName);
      },
      /**
        To get the values of multiple properties at once, call `getProperties`
        with a list of strings or an array:
        ```javascript
        record.getProperties('firstName', 'lastName', 'zipCode');
        // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
        ```
        is equivalent to:
        ```javascript
        record.getProperties(['firstName', 'lastName', 'zipCode']);
        // { firstName: 'John', lastName: 'Doe', zipCode: '10011' }
        ```
        @method getProperties
        @param {String...|Array} list of keys to get
        @return {Hash}
      */
      getProperties: function() {
        return apply(null, getProperties, [this].concat(slice.call(arguments)));
      },
      /**
        Sets the provided key or path to the value.
        This method is generally very similar to calling `object[key] = value` or
        `object.key = value`, except that it provides support for computed
        properties, the `setUnknownProperty()` method and property observers.
        ### Computed Properties
        If you try to set a value on a key that has a computed property handler
        defined (see the `get()` method for an example), then `set()` will call
        that method, passing both the value and key instead of simply changing
        the value itself. This is useful for those times when you need to
        implement a property that is composed of one or more member
        properties.
        ### Unknown Properties
        If you try to set a value on a key that is undefined in the target
        object, then the `setUnknownProperty()` handler will be called instead. This
        gives you an opportunity to implement complex "virtual" properties that
        are not predefined on the object. If `setUnknownProperty()` returns
        undefined, then `set()` will simply set the value on the object.
        ### Property Observers
        In addition to changing the property, `set()` will also register a property
        change with the object. Unless you have placed this call inside of a
        `beginPropertyChanges()` and `endPropertyChanges(),` any "local" observers
        (i.e. observer methods declared on the same object), will be called
        immediately. Any "remote" observers (i.e. observer methods declared on
        another object) will be placed in a queue and called at a later time in a
        coalesced manner.
        ### Chaining
        In addition to property changes, `set()` returns the value of the object
        itself so you can do chaining like this:
        ```javascript
        record.set('firstName', 'Charles').set('lastName', 'Jolley');
        ```
        @method set
        @param {String} keyName The property to set
        @param {Object} value The value to set or `null`.
        @return {Ember.Observable}
      */
      set: function(keyName, value) {
        set(this, keyName, value);
        return this;
      },
      /**
        Sets a list of properties at once. These properties are set inside
        a single `beginPropertyChanges` and `endPropertyChanges` batch, so
        observers will be buffered.
        ```javascript
        record.setProperties({ firstName: 'Charles', lastName: 'Jolley' });
        ```

        return setProperties(this, hash);
      },

        Adds an observer on a property.
        This is the core method used to register an observer for a property.
        Once you call this method, any time the key's value is set, your observer
        will be notified. Note that the observers are triggered any time the
        value is set, regardless of whether it has actually changed. Your
        observer should be prepared to handle that.
        You can also pass an optional context parameter to this method. The
        context will be passed to your observer method whenever it is triggered.
        Note that if you add the same target/method pair on a key multiple times
        with different context parameters, your observer will only be called once
        with the last context you passed.
        ### Observer Methods
        Observer methods you pass should generally have the following signature if
        you do not pass a `context` parameter:
        ```javascript
        fooDidChange: function(sender, key, value, rev) { };
        ```
        The sender is the object that changed. The key is the property that
        changes. The value property is currently reserved and unused. The rev
        is the last property revision of the object when it changed, which you can
        use to detect if the key value has really changed or not.
        If you pass a `context` parameter, the context will be passed before the
        revision like so:
        ```javascript
        fooDidChange: function(sender, key, value, context, rev) { };
        ```
        Usually you will not need the value, context or revision parameters at
        the end. In this case, it is common to write observer methods that take
        only a sender and key value as parameters or, if you aren't interested in
        any of these values, to write an observer that has no parameters at all.
        @method addObserver
        @param {String} key The key to observer

      controller.get('isRejected')  //=> false

      As the controller is an ObjectController, and the json now its content,
      all the json properties will be available directly from the controller.

      // both properties will accessible on the controller
      controller.get('firstName') //=> 'Stefan'
      controller.get('lastName')  //=> 'Penner'

      `Ember.SortableMixin` provides a standard interface for array proxies
      to specify a sort order and maintain this sorting when objects are added,
      removed, or updated without changing the implicit order of their underlying
      modelarray:
      ```javascript
      songs = [
        {trackNumber: 4, title: 'Ob-La-Di, Ob-La-Da'},
        {trackNumber: 2, title: 'Back in the U.S.S.R.'},
        {trackNumber: 3, title: 'Glass Onion'},
      ];

        model: songs,

      songsController.addObject({trackNumber: 1, title: 'Dear Prudence'});
      songsController.get('firstObject');  // {trackNumber: 1, title: 'Dear Prudence'}
      ```
      If you add or remove the properties to sort by or change the sort direction the model
      sort order will be automatically updated.
      ```javascript
      songsController.set('sortProperties', ['title']);
      songsController.get('firstObject'); // {trackNumber: 2, title: 'Back in the U.S.S.R.'}
      songsController.toggleProperty('sortAscending');
      songsController.get('firstObject'); // {trackNumber: 4, title: 'Ob-La-Di, Ob-La-Da'}
      ```
      SortableMixin works by sorting the arrangedContent array, which is the array that
      arrayProxy displays. Due to the fact that the underlying 'content' array is not changed, that
      array will not display the sorted list:
       ```javascript
      songsController.get('content').get('firstObject'); // Returns the unsorted original content
      songsController.get('firstObject'); // Returns the sorted content.
      ```
      Although the sorted content can also be accessed through the arrangedContent property,
      it is preferable to use the proxied class and not the arrangedContent array directly.

      An ArrayProxy wraps any other object that implements `Ember.Array` and/or
      `Ember.MutableArray,` forwarding all requests. This makes it very useful for
      a number of binding use cases or other cases where being able to swap
      out the underlying array is useful.
      A simple example of usage:
      ```javascript
      var pets = ['dog', 'cat', 'fish'];
      var ap = Ember.ArrayProxy.create({ content: Ember.A(pets) });
      ap.get('firstObject');                        // 'dog'

      ap.get('firstObject');                        // 'amoeba'
      ```
      This class can also be useful as a layer to transform the contents of
      an array, as they are accessed. This can be done by overriding
      `objectAtContent`:
      ```javascript
      var pets = ['dog', 'cat', 'fish'];
      var ap = Ember.ArrayProxy.create({
          content: Ember.A(pets),

              return this.get('content').objectAt(idx).toUpperCase();

      });
      ap.get('firstObject'); // . 'DOG'

        NOTE: If you do override `init` for a framework class like `Ember.View` or
        `Ember.ArrayController`, be sure to call `this._super()` in your
        `init` declaration! If you don't, Ember may not have an opportunity to
        do important setup work, and you'll see strange behavior in your
        application.
        @method init
      */
      init: function() {},
      /**
        Defines the properties that will be concatenated from the superclass
        (instead of overridden).
        By default, when you extend an Ember class a property defined in
        the subclass overrides a property with the same name that is defined
        in the superclass. However, there are some cases where it is preferable
        to build up a property's value by combining the superclass' property
        value with the subclass' value. An example of this in use within Ember
        is the `classNames` property of `Ember.View`.
        Here is some sample code showing the difference between a concatenated
        property and a normal one:
        ```javascript
        App.BarView = Ember.View.extend({
          someNonConcatenatedProperty: ['bar'],
          classNames: ['bar']
        });
        App.FooBarView = App.BarView.extend({
          someNonConcatenatedProperty: ['foo'],
          classNames: ['foo']
        });
        var fooBarView = App.FooBarView.create();
        fooBarView.get('someNonConcatenatedProperty'); // ['foo']
        fooBarView.get('classNames'); // ['ember-view', 'bar', 'foo']
        ```
        This behavior extends to object creation as well. Continuing the
        above example:
        ```javascript
        var view = App.FooBarView.create({
          someNonConcatenatedProperty: ['baz'],
          classNames: ['baz']
        })
        view.get('someNonConcatenatedProperty'); // ['baz']
        view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
        ```
        Adding a single property that is not an array will just add it in the array:
        ```javascript
        var view = App.FooBarView.create({
          classNames: 'baz'
        })
        view.get('classNames'); // ['ember-view', 'bar', 'foo', 'baz']
        ```
        Using the `concatenatedProperties` property, we can tell to Ember that mix
        the content of the properties.
        In `Ember.View` the `classNameBindings` and `attributeBindings` properties
        are also concatenated, in addition to `classNames`.
        This feature is available for you to use throughout the Ember object model,
        although typical app developers are likely to use it infrequently. Since
        it changes expectations about behavior of properties, you should properly
        document its usage in each individual concatenated property (to not
        mislead your users to think they can override the property in a subclass).

        person = App.Person.create()

        ```
        If the object's class is not defined on an Ember namespace, it will

        Creates a new subclass.
        ```javascript
        App.Person = Ember.Object.extend({
          say: function(thing) {
            alert(thing);
           }
        });
        ```
        This defines a new subclass of Ember.Object: `App.Person`. It contains one method: `say()`.
        You can also create a subclass from any existing class by calling its `extend()`  method. For example, you might want to create a subclass of Ember's built-in `Ember.View` class:
        ```javascript
        App.PersonView = Ember.View.extend({
          tagName: 'li',
          classNameBindings: ['isAdministrator']
        });
        ```
        When defining a subclass, you can override methods but still access the implementation of your parent class by calling the special `_super()` method:
        ```javascript
        App.Person = Ember.Object.extend({
          say: function(thing) {
            var name = this.get('name');
            alert(name + ' says: ' + thing);
          }
        });
        App.Soldier = App.Person.extend({
          say: function(thing) {
            this._super(thing + ", sir!");
          },
          march: function(numberOfHours) {
            alert(this.get('name') + ' marches for ' + numberOfHours + ' hours.')
          }
        });
        var yehuda = App.Soldier.create({
          name: "Yehuda Katz"
        });
        yehuda.say("Yes");  // alerts "Yehuda Katz says: Yes, sir!"
        ```
        The `create()` on line #17 creates an *instance* of the `App.Soldier` class. The `extend()` on line #8 creates a *subclass* of `App.Person`. Any instance of the `App.Person` class will *not* have the `march()` method.
        You can also pass `Mixin` classes to add additional properties to the subclass.
        ```javascript
        App.Person = Ember.Object.extend({
          say: function(thing) {

    /**
      An unordered collection of objects.
      A Set works a bit like an array except that its items are not ordered. You
      can create a set to efficiently test for membership for an object. You can
      also iterate through a set just like an array, even accessing objects by
      index, however there is no guarantee as to their order.
      All Sets are observable via the Enumerable Observer API - which works
      on any enumerable object including both Sets and Arrays.
      ## Creating a Set
      You can create a set like you would most objects using
      `new Ember.Set()`. Most new sets you create will be empty, but you can
      also initialize the set with some content by passing an array or other
      enumerable of objects to the constructor.
      Finally, you can pass in an existing set and the set will be copied. You
      can also create a copy of a set by calling `Ember.Set#copy()`.
      ```javascript
      // creates a new empty set
      var foundNames = new Ember.Set();
      // creates a set with four names in it.
      var names = new Ember.Set(["Charles", "Tom", "Juan", "Alex"]); // :P
      // creates a copy of the names set.
      var namesCopy = new Ember.Set(names);
      // same as above.
      var anotherNamesCopy = names.copy();
      ```
      ## Adding/Removing Objects
      You generally add or remove objects from a set using `add()` or
      `remove()`. You can add any type of object including primitives such as
      numbers, strings, and booleans.
      Unlike arrays, objects can only exist one time in a set. If you call `add()`
      on a set with the same object multiple times, the object will only be added
      once. Likewise, calling `remove()` with the same object multiple times will
      remove the object the first time and have no effect on future calls until
      you add the object to the set again.
      NOTE: You cannot add/remove `null` or `undefined` to a set. Any attempt to do
      so will be ignored.
      In addition to add/remove you can also call `push()`/`pop()`. Push behaves
      just like `add()` but `pop()`, unlike `remove()` will pick an arbitrary
      object, remove it and return it. This is a good way to use a set as a job
      queue when you don't care which order the jobs are executed in.
      ## Testing for an Object
      To test for an object's presence in a set you simply call
      `Ember.Set#contains()`.
      ## Observing changes
      When using `Ember.Set`, you can observe the `"[]"` property to be
      alerted whenever the content changes. You can also add an enumerable
      observer to the set to be notified of specific objects that are added and
      removed from the set. See [Ember.Enumerable](/api/classes/Ember.Enumerable.html)
      for more information on enumerables.
      This is often unhelpful. If you are filtering sets of objects, for instance,
      it is very inefficient to re-filter all of the items each time the set
      changes. It would be better if you could just adjust the filtered set based
      on what was changed on the original set. The same issue applies to merging
      sets, as well.
      ## Other Methods
      `Ember.Set` primary implements other mixin APIs. For a complete reference
      on the methods you will use with `Ember.Set`, please consult these mixins.
      The most useful ones will be `Ember.Enumerable` and
      `Ember.MutableEnumerable` which implement most of the common iterator
      methods you are used to on Array.
      Note that you can also use the `Ember.Copyable` and `Ember.Freezable`
      APIs on `Ember.Set` as well. Once a set is frozen it can no longer be
      modified. The benefit of this is that when you call `frozenCopy()` on it,
      Ember will avoid making copies of the set. This allows you to write
      code that can know with certainty when the underlying set data will or
      will not be modified.

      `RSVP.allSettled` is similar to `RSVP.all`, but instead of implementing
      a fail-fast method, it waits until all the promises have returned and
      shows you all the results. This is useful if you want to handle multiple
      promises' failure states together as a set.
      Returns a promise that is fulfilled when all the given promises have been
      settled. The return promise is fulfilled with an array of the states of
      the promises passed into the `promises` array argument.
      Each state object will either indicate fulfillment or rejection, and
      provide the corresponding value or reason. The states will take one of
      the following formats:
      ```javascript
      { state: 'fulfilled', value: value }
        or
      { state: 'rejected', reason: reason }
      ```
      Example:
      ```javascript
      var promise1 = RSVP.Promise.resolve(1);
      var promise2 = RSVP.Promise.reject(new Error('2'));
      var promise3 = RSVP.Promise.reject(new Error('3'));

        //   { state: 'rejected', reason: Error }
        // ]
        // Note that for the second item, reason.message will be '2', and for the
        // third item, reason.message will be '3'.
      }, function(error) {

      `RSVP.defer` returns an object similar to jQuery's `$.Deferred`.
      `RSVP.defer` should be used when porting over code reliant on `$.Deferred`'s
      interface. New code should use the `RSVP.Promise` constructor instead.
      The object returned from `RSVP.defer` is a plain object with three properties:
      * promise - an `RSVP.Promise`.
      * reject - a function that causes the `promise` property on this object to
        become rejected
      * resolve - a function that causes the `promise` property on this object to
        become fulfilled.
      Example:
       ```javascript
       var deferred = RSVP.defer();
       deferred.resolve("Success!");
       defered.promise.then(function(value){
         // value here is "Success!"

     `RSVP.filter` is similar to JavaScript's native `filter` method, except that it
      waits for all promises to become fulfilled before running the `filterFn` on
      each item in given to `promises`. `RSVP.filter` returns a promise that will
      become fulfilled with the result of running `filterFn` on the values the
      promises become fulfilled with.
      For example:
      ```javascript
      var promise1 = RSVP.resolve(1);
      var promise2 = RSVP.resolve(2);
      var promise3 = RSVP.resolve(3);
      var promises = [promise1, promise2, promise3];

      });
      ```
      If any of the `promises` given to `RSVP.filter` are rejected, the first promise
      that is rejected will be given as an argument to the returned promise's
      rejection handler. For example:
      ```javascript
      var promise1 = RSVP.resolve(1);
      var promise2 = RSVP.reject(new Error('2'));
      var promise3 = RSVP.reject(new Error('3'));
      var promises = [ promise1, promise2, promise3 ];
      var filterFn = function(item){
        return item > 1;
      };
      RSVP.filter(promises, filterFn).then(function(array){
        // Code here never runs because there are rejected promises!
      }, function(reason) {
        // reason.message === '2'
      });
      ```
      `RSVP.filter` will also wait for any promises returned from `filterFn`.
      For instance, you may want to fetch a list of users then return a subset
      of those users based on some asynchronous operation:
      ```javascript
      var alice = { name: 'alice' };
      var bob   = { name: 'bob' };
      var users = [ alice, bob ];
      var promises = users.map(function(user){

      });
      var filterFn = function(user){
        // Here, Alice has permissions to create a blog post, but Bob does not.
        return getPrivilegesForUser(user).then(function(privs){
          return privs.can_create_blog_post === true;
        });
      };
      RSVP.filter(promises, filterFn).then(function(users){
        // true, because the server told us only Alice can create a blog post.
        users.length === 1;
        // false, because Alice is the only user present in `users`

      `RSVP.hashSettled` is similar to `RSVP.allSettled`, but takes an object
      instead of an array for its `promises` argument.
      Unlike `RSVP.all` or `RSVP.hash`, which implement a fail-fast method,
      but like `RSVP.allSettled`, `hashSettled` waits until all the
      constituent promises have returned and then shows you all the results
      with their states and values/reasons. This is useful if you want to
      handle multiple promises' failure states together as a set.
      Returns a promise that is fulfilled when all the given promises have been
      settled, or rejected if the passed parameters are invalid.
      The returned promise is fulfilled with a hash that has the same key names as
      the `promises` object argument. If any of the values in the object are not
      promises, they will be copied over to the fulfilled object and marked with state
      'fulfilled'.
      Example:
      ```javascript
      var promises = {
        myPromise: RSVP.Promise.resolve(1),
        yourPromise: RSVP.Promise.resolve(2),
        theirPromise: RSVP.Promise.resolve(3),
        notAPromise: 4
      };
      RSVP.hashSettled(promises).then(function(hash){
        // hash here is an object that looks like:
        // {
        //   myPromise: { state: 'fulfilled', value: 1 },
        //   yourPromise: { state: 'fulfilled', value: 2 },
        //   theirPromise: { state: 'fulfilled', value: 3 },
        //   notAPromise: { state: 'fulfilled', value: 4 }
        // }
      });
      ```
      If any of the `promises` given to `RSVP.hash` are rejected, the state will
      be set to 'rejected' and the reason for rejection provided.
      Example:
      ```javascript
      var promises = {
        myPromise: RSVP.Promise.resolve(1),
        rejectedPromise: RSVP.Promise.reject(new Error('rejection')),
        anotherRejectedPromise: RSVP.Promise.reject(new Error('more rejection')),
      };
      RSVP.hashSettled(promises).then(function(hash){
        // hash here is an object that looks like:
        // {

      `RSVP.hash` is similar to `RSVP.all`, but takes an object instead of an array
      for its `promises` argument.
      Returns a promise that is fulfilled when all the given promises have been
      fulfilled, or rejected if any of them become rejected. The returned promise
      is fulfilled with a hash that has the same key names as the `promises` object
      argument. If any of the values in the object are not promises, they will
      simply be copied over to the fulfilled object.

     `RSVP.map` is similar to JavaScript's native `map` method, except that it
      waits for all promises to become fulfilled before running the `mapFn` on
      each item in given to `promises`. `RSVP.map` returns a promise that will
      become fulfilled with the result of running `mapFn` on the values the promises
      become fulfilled with.
      For example:
      ```javascript
      var promise1 = RSVP.resolve(1);
      var promise2 = RSVP.resolve(2);
      var promise3 = RSVP.resolve(3);
      var promises = [ promise1, promise2, promise3 ];
      var mapFn = function(item){
        return item + 1;
      };
      RSVP.map(promises, mapFn).then(function(result){
        // result is [ 2, 3, 4 ]
      });
      ```
      If any of the `promises` given to `RSVP.map` are rejected, the first promise
      that is rejected will be given as an argument to the returned promise's
      rejection handler. For example:
      ```javascript
      var promise1 = RSVP.resolve(1);
      var promise2 = RSVP.reject(new Error('2'));
      var promise3 = RSVP.reject(new Error('3'));
      var promises = [ promise1, promise2, promise3 ];
      var mapFn = function(item){
        return item + 1;
      };
      RSVP.map(promises, mapFn).then(function(array){
        // Code here never runs because there are rejected promises!
      }, function(reason) {
        // reason.message === '2'
      });
      ```
      `RSVP.map` will also wait if a promise is returned from `mapFn`. For example,
      say you want to get all comments from a set of blog posts, but you need
      the blog posts first because they contain a url to those comments.
      ```javscript
      var mapFn = function(blogPost){
        // getComments does some ajax and returns an RSVP.Promise that is fulfilled
        // with some comments data
        return getComments(blogPost.comments_url);
      };
      // getBlogPosts does some ajax and returns an RSVP.Promise that is fulfilled
      // with some blog post data
      RSVP.map(getBlogPosts(), mapFn).then(function(comments){
        // comments is the result of asking the server for the comments
        // of all blog posts returned from getBlogPosts()
      });
      ```

    /**
      `RSVP.denodeify` takes a 'node-style' function and returns a function that
      will return an `RSVP.Promise`. You can use `denodeify` in Node.js or the
      browser when you'd prefer to use promises over using callbacks. For example,
      `denodeify` transforms the following:
      ```javascript
      var fs = require('fs');
      fs.readFile('myfile.txt', function(err, data){
        if (err) return handleError(err);
        handleData(data);
      });
      ```
      into:
      ```javascript
      var fs = require('fs');
      var readFile = RSVP.denodeify(fs.readFile);
      readFile('myfile.txt').then(handleData, handleError);
      ```
      If the node function has multiple success parameters, then `denodeify`
      just returns the first one:
      ```javascript
      var request = RSVP.denodeify(require('request'));
      request('http://example.com').then(function(res) {
        // ...
      });
      ```
      However, if you need all success parameters, setting `denodeify`'s
      second parameter to `true` causes it to return all success parameters
      as an array:
      ```javascript
      var request = RSVP.denodeify(require('request'), true);
      request('http://example.com').then(function(result) {
        // result[0] -> res
        // result[1] -> body
      });
      ```
      Or if you pass it an array with names it returns the parameters as a hash:
      ```javascript
      var request = RSVP.denodeify(require('request'), ['res', 'body']);
      request('http://example.com').then(function(result) {
        // result.res
        // result.body
      });
      ```
      Sometimes you need to retain the `this`:
      ```javascript
      var app = require('express')();
      var render = RSVP.denodeify(app.render.bind(app));
      ```
      The denodified function inherits from the original function. It works in all
      environments, except IE 10 and below. Consequently all properties of the original
      function are available to you. However, any properties you change on the
      denodeified function won't be changed on the original function. Example:
      ```javascript
      var request = RSVP.denodeify(require('request')),
          cookieJar = request.jar(); // <- Inheritance is used here
      request('http://example.com', {jar: cookieJar}).then(function(res) {
        // cookieJar.cookies holds now the cookies returned by example.com
      });
      ```
      Using `denodeify` makes it easier to compose asynchronous operations instead
      of using callbacks. For example, instead of:
      ```javascript
      var fs = require('fs');
      fs.readFile('myfile.txt', function(err, data){
        if (err) { ... } // Handle error
        fs.writeFile('myfile2.txt', data, function(err){
          if (err) { ... } // Handle error
          console.log('done')
        });
      });
      ```
      you can chain the operations together using `then` from the returned promise:
      ```javascript
      var fs = require('fs');
      var readFile = RSVP.denodeify(fs.readFile);
      var writeFile = RSVP.denodeify(fs.writeFile);
      readFile('myfile.txt').then(function(data){
        return writeFile('myfile2.txt', data);
      }).then(function(){
        console.log('done')
      }).catch(function(error){
        // Handle error
      });
      ```
      @method denodeify
      @static
      @for RSVP
      @param {Function} nodeFunc a 'node-style' function that takes a callback as
      its last argument. The callback expects an error to be passed as its first
      argument (if an error occurred, otherwise null), and the value from the
      operation as its second argument ('function(err, value){ }').
      @param {Boolean|Array} argumentNames An optional paramter that if set
      to `true` causes the promise to fulfill with the callback's success arguments
      as an array. This is useful if the node function has multiple success
      paramters. If you set this paramter to an array with names, the promise will
      fulfill with a hash with these names as keys and the success parameters as
      values.

    /**
      Promise objects represent the eventual result of an asynchronous operation. The
      primary way of interacting with a promise is through its `then` method, which
      registers callbacks to receive either a promise’s eventual value or the reason
      why the promise cannot be fulfilled.
      Terminology
      -----------
      - `promise` is an object or function with a `then` method whose behavior conforms to this specification.
      - `thenable` is an object or function that defines a `then` method.
      - `value` is any legal JavaScript value (including undefined, a thenable, or a promise).
      - `exception` is a value that is thrown using the throw statement.
      - `reason` is a value that indicates why a promise was rejected.
      - `settled` the final resting state of a promise, fulfilled or rejected.
      A promise can be in one of three states: pending, fulfilled, or rejected.
      Promises that are fulfilled have a fulfillment value and are in the fulfilled
      state.  Promises that are rejected have a rejection reason and are in the
      rejected state.  A fulfillment value is never a thenable.
      Promises can also be said to *resolve* a value.  If this value is also a
      promise, then the original promise's settled state will match the value's
      settled state.  So a promise that *resolves* a promise that rejects will
      itself reject, and a promise that *resolves* a promise that fulfills will
      itself fulfill.
      Basic Usage:
      ------------
      ```js
      var promise = new Promise(function(resolve, reject) {
        // on success
        resolve(value);
        // on failure
        reject(reason);
      });
      promise.then(function(value) {
        // on fulfillment
      }, function(reason) {
        // on rejection
      });
      ```
      Advanced Usage:
      ---------------
      Promises shine when abstracting away asynchronous interactions such as
      `XMLHttpRequest`s.
      ```js
      function getJSON(url) {
        return new Promise(function(resolve, reject){
          var xhr = new XMLHttpRequest();
          xhr.open('GET', url);
          xhr.onreadystatechange = handler;
          xhr.responseType = 'json';
          xhr.setRequestHeader('Accept', 'application/json');
          xhr.send();
          function handler() {
            if (this.readyState === this.DONE) {
              if (this.status === 200) {
                resolve(this.response);
              } else {
                reject(new Error('getJSON: `' + url + '` failed with status: [' + this.status + ']'));
              }
            }
          };
        });
      }
      getJSON('/posts.json').then(function(json) {
        // on fulfillment
      }, function(reason) {
        // on rejection
      });
      ```
      Unlike callbacks, promises are great composable primitives.
      ```js
      Promise.all([
        getJSON('/posts'),
        getJSON('/comments')
      ]).then(function(values){
        values[0] // => postsJSON
        values[1] // => commentsJSON
        return values;
      });
      ```
      @class RSVP.Promise
      @param {function} resolver
      @param {String} label optional string for labeling the promise.
      Useful for tooling.
      @constructor
    */
    function Promise(resolver, label) {
      this._id = counter++;
      this._label = label;
      this._state = undefined;
      this._result = undefined;
      this._subscribers = [];
      if (config.instrument) {
        instrument('created', this);
      }
      if (noop !== resolver) {
        if (!isFunction(resolver)) {
          needsResolver();
        }
        if (!(this instanceof Promise)) {
          needsNew();
        }
        initializePromise(this, resolver);
      }
    }
    Promise.cast = Resolve; // deprecated
    Promise.all = all;
    Promise.race = race;
    Promise.resolve = Resolve;
    Promise.reject = Reject;
    Promise.prototype = {
      constructor: Promise,
      _guidKey: guidKey,
      _onerror: function (reason) {
        config.trigger('error', reason);
      },
    /**
      The primary way of interacting with a promise is through its `then` method,
      which registers callbacks to receive either a promise's eventual value or the
      reason why the promise cannot be fulfilled.
      ```js
      findUser().then(function(user){
        // user is available
      }, function(reason){
        // user is unavailable, and you are given the reason why
      });
      ```
      Chaining
      --------
      The return value of `then` is itself a promise.  This second, 'downstream'
      promise is resolved with the return value of the first promise's fulfillment
      or rejection handler, or rejected if the handler throws an exception.
      ```js
      findUser().then(function (user) {
        return user.name;
      }, function (reason) {
        return 'default name';
      }).then(function (userName) {
        // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
        // will be `'default name'`
      });
      findUser().then(function (user) {
        throw new Error('Found user, but still unhappy');
      }, function (reason) {
        throw new Error('`findUser` rejected and we're unhappy');
      }).then(function (value) {
        // never reached
      }, function (reason) {
        // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
        // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
      });
      ```
      If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
      ```js
      findUser().then(function (user) {
        throw new PedagogicalException('Upstream error');
      }).then(function (value) {
        // never reached
      }).then(function (value) {
        // never reached
      }, function (reason) {
        // The `PedgagocialException` is propagated all the way down to here
      });
      ```
      Assimilation
      ------------
      Sometimes the value you want to propagate to a downstream promise can only be
      retrieved asynchronously. This can be achieved by returning a promise in the
      fulfillment or rejection handler. The downstream promise will then be pending
      until the returned promise is settled. This is called *assimilation*.
      ```js
      findUser().then(function (user) {
        return findCommentsByAuthor(user);
      }).then(function (comments) {
        // The user's comments are now available
      });
      ```
      If the assimliated promise rejects, then the downstream promise will also reject.
      ```js
      findUser().then(function (user) {
        return findCommentsByAuthor(user);
      }).then(function (comments) {
        // If `findCommentsByAuthor` fulfills, we'll have the value here
      }, function (reason) {
        // If `findCommentsByAuthor` rejects, we'll have the reason here
      });
      ```

      var result;
      try {
        result = findResult();

      promise.then(function(value){
        // value === 1
      });

      `RSVP.rethrow` will rethrow an error on the next turn of the JavaScript event
      loop in order to aid debugging.
      Promises A+ specifies that any exceptions that occur with a promise must be
      caught by the promises implementation and bubbled to the last handler. For
      this reason, it is recommended that you always specify a second rejection
      handler function to `then`. However, `RSVP.rethrow` will throw the exception
      outside of the promise, so it bubbles up to your console if in the browser,
      or domain/cause uncaught exception in Node. `rethrow` will also throw the
      error again so the error can be handled by the promise per the spec.
      ```javascript
      function throws(){
        throw new Error('Whoops!');
      }
      var promise = new RSVP.Promise(function(resolve, reject){
        throws();
      });
      promise.catch(RSVP.rethrow).then(function(){
        // Code here doesn't run because the promise became rejected due to an
        // error!
      }, function (err){
        // handle the error here
      });
      ```
      The 'Whoops' error will be thrown on the next turn of the event loop
      and you can watch for it in your console. You can also handle it using a
      rejection handler given to `.then` or `.catch` on the returned promise.
      @method rethrow

      @param {Error} reason reason the promise became rejected.
