Asyncio Support

[aaronclong]

I wondered if you gave any consideration towards supporting asyncio with this library. It is a growing trend within Python because of its performance improvements. Knowingly, it would require a massive change in the library, so not something super feasible in the short term. Besides the API and behavioral changes, it would require adding an optional network library to make HTTP calls in an async manner (aiohttp). Python doesn't/can't support asyncio because of the profound changes required to the contract.
