Easy mocking for easy testing.

## Instructions

It's as simple as:

```elixir
defmodule SomeTest do
  import Stitch

  test "calling IO.puts" do
    stitch IO, ["puts"] do  
      result = Mymodule.func("pandoro")
      # Assume func = fn x -> IO.puts(x) end

      assert called(IO.puts("pandoro"))
      assert result == "puts/1"
    end
  end
end
```

If you need a specific value:

```elixir
test "calling IO.puts" do
  stitch IO, [{"puts/1", :value}] do  
    result = Mymodule.func("pandoro")

    assert called(IO.puts("pandoro"))
    assert result == :value
  end
end
```
