// Phoenix Channels JavaScript client
//
// ## Socket Connection
//
// A single connection is established to the server and
// channels are mulitplexed over the connection.
// Connect to the server using the `Socket` class:
//
//     let socket = new Socket("/ws")
//     socket.connect()
//
// The `Socket` constructor takes the mount point of the socket
// as well as options that can be found in the Socket docs,
// such as configuring the `LongPoller` transport, and heartbeat.
//
//
// ## Channels
//
// Channels are isolated, concurrent processes on the server that
// subscribe to topics and broker events between the client and server.
// To join a channel, you must provide the topic, and channel params for
// authorization. Here's an example chat room example where `"new_msg"`
// events are listened for, messages are pushed to the server, and
// the channel is joined with ok/error matches, and `after` hook:
//
//     let chan = socket.chan("rooms:123", {token: roomToken})
//     chan.on("new_msg", msg => console.log("Got message", msg) )
//     $input.onEnter( e => {
//       chan.push("new_msg", {body: e.target.val})
//           .receive("ok", (message) => console.log("created message", message) )
//           .receive("error", (reasons) => console.log("create failed", reasons) )
//           .after(10000, () => console.log("Networking issue. Still waiting...") )
//     })
//     chan.join()
//         .receive("ok", ({messages}) => console.log("catching up", messages) )
//         .receive("error", ({reason}) => console.log("failed join", reason) )
//         .after(10000, () => console.log("Networking issue. Still waiting...") )
//
//
// ## Joining
//
// Joining a channel with `chan.join(topic, params)`, binds the params to
// `chan.params`. Subsequent rejoins will send up the modified params for
// updating authorization params, or passing up last_message_id information.
// Successful joins receive an "ok" status, while unsuccessful joins
// receive "error".
//
//
// ## Pushing Messages
//
// From the prevoius example, we can see that pushing messages to the server
// can be done with `chan.push(eventName, payload)` and we can optionally
// receive responses from the push. Additionally, we can use
// `after(millsec, callback)` to abort waiting for our `receive` hooks and
// take action after some period of waiting.
//
//
// ## Socket Hooks
//
// Lifecycle events of the multiplexed connection can be hooked into via
// `socket.onError()` and `socket.onClose()` events, ie:
//
//     socket.onError( () => console.log("there was an error with the connection!") )
//     socket.onClose( () => console.log("the connection dropped") )
//
//
// ## Channel Hooks
//
// For each joined channel, you can bind to `onError` and `onClose` events
// to monitor the channel lifecycle, ie:
//
//     chan.onError( () => console.log("there was an error!") )
//     chan.onClose( () => console.log("the channel has gone away gracefully") )
//
// ### onError hooks
//
// `onError` hooks are invoked if the socket connection drops, or the channel
// crashes on the server. In either case, a channel rejoin is attemtped
// automatically in an exponential backoff manner.
//
// ### onClose hooks
//
// `onClose` hooks are invoked only in two cases. 1) the channel explicitly
// closed on the server, or 2). The client explicitly closed, by calling
// `chan.leave()`
//
