Flask evolution

(The author) sees Quart as an evolution of Flask, primarily to support asyncio and secondarily to support websockets and HTTP/2. These additions are designed following (the author’s interpretation) of Flask’s design choices. It is for this reason that the websocket context and global exist, rather than as an argument to the route handler. The details of HTTP/2 are also abstracted into the serving layer allowing Quart to remain a micro framework.
