What is later?

later is a play on Async not happening now but at some point in the future. It was also an awesome name for a toolkit for writing AsyncIO applications. The batteries if you will for AsyncIO.

later offers the following functions:

- **asyncio** `Event` enhancements
    - ``BiDirectionalEvent`` - Back channel of information for the setter to ensure the waiter has called wait() a second time
- **asyncio** `Task` enhancements
    - `Watcher` - Watch tasks and ensure they don't die - take action when they do
- **asyncio** Unittesting enhancements
    - `TestCase` - Use in place of `IsolatedAsyncioTestCase` for more wins
    - `IsolatedAsyncioTestCase` is backported for 3.7 users

later currently backports 3.8's async_case + mock libraries for 3.7 users.
