When the Signal is triggered using its ``send()`` method, all connected callbacks will be scheduled for asynchronous execution.\r\n\r\nConnections can optionally be made with two types of filters, ``senders`` and ``keys``. If filters are used, the callback is only scheduled for execution if the Signal is sent with at least one matching ``sender`` or ``key``. A ``sender`` can be any object, while a ``key`` is more likely to be a ``string``. Under the hood, they use ``id()`` and ``hash()`` respectively.\r\n\r\nCallbacks are invoked with keyword arguments that allow the callback to determine which Signal is calling it and which ``senders`` and ``keys`` were specified. Additional keyword arguments can be added to the Signal when it is instantiated, and their default values can be replaced when the Signal is sent.\r\n\r\nExample\r\n-------\r\n\r\n.. code:: python\r\n\r\n    import asyncio\r\n    from asyncio_dispatch import Signal\r\n    \r\n    \r\n    @asyncio.coroutine\r\n    def callback(**kwargs):\r\n        print('callback was called!')\r\n    \r\n    \r\n    loop = asyncio.get_event_loop()\r\n    \r\n    # create the signal\r\n    signal = Signal(loop=loop)\r\n    \r\n    # connect the callback to the Signal - This is a coroutine!\r\n    loop.run_until_complete(loop.create_task(signal.connect(callback)))\r\n    \r\n    # send the signal - This is also a coroutine!\r\n    print('sending the signal.')\r\n    loop.run_until_complete(loop.create_task(signal.send()))\r\n    \r\n    \r\nThe above example will print the following:\r\n\r\n.. code:: bash\r\n\r\n    sending the signal.\r\n    callback was called!\r\n    \r\nFeatures\r\n--------\r\n\r\n* Supports the new async/await syntax found in python 3.5 and up\r\n* Callbacks can be a function, asyncio.coroutine, async def, class method, @staticmethod, or @classmethod\r\n* Multiple callbacks can be connected to the same signal\r\n* Callbacks can be called with additional keyword arguments containing references to arbitrary objects\r\n* Callbacks can be disconnected from a signal\r\n* Signals can hold weak or strong references to callbacks, allowing for automatic disconnection if a reference to a callback is not maintained, or conversely to persist one-off ``lambda`` expressions without needing to maintain a reference\r\n* Callbacks receive the ``Signal`` object that was used to schedule it, so multiple signals can be attached to the same callback and handled differently\r\n* Callbacks can be connected with ``senders`` or ``keys`` which cause the Signal to ignore the callback unless the signal is sent with a matching *Object* or *str* \r\n\r\nLicense\r\n-------\r\n\r\nReleased under the MIT license.\r\n\r\nInstallation\r\n------------\r\n.. code:: bash\r\n    \r\n    pip install asyncio_dispatch",
