Context

It provides APIs to get some detail information of context or one specific worker. In the multirunnable realm, worker could be mean process, thread, green thread or async task with different strategy.

Below are the mapping table of worker with different strategy and Python package:

Worker	Python Package	Strategy
Process	multiprocessing	Parallel
Thread	threading	Concurrent
Green Thread	gevent	GreenThread
Async Task	asyncio	Asynchronous

Context

module multirunnable.adapter

This module be an adapter to get the context of mapping worker with RunningMode so that it doesn’t need to use different object of different sub-package. It also could get the context via module in each strategy.
