Message transfer in each direction is simple: IO receives a byte stream [1] and
sends this stream for parsing. The parser will periodically emit a complete
message text on the Messages stream [2]. Similarly, when messages are written
to the Messages stream [3], they are framed using the WebSocket wire format and
emitted via IO [4].

There is a feedback loop via [5] since some input from [1] will be things like
ping, pong and close frames. In these cases the protocol responds by emitting
responses directly back to [4] rather than emitting messages via [2].

For the purposes of flow control, we consider the sources of each Readable
stream to be as follows:

* [2] receives input from [1]
* [4] receives input from [1] and [3]

The classes below express the relationships described above without prescribing
anything about how parse() and frame() work, other than assuming they emit
'data' events to the IO and Messages streams. They will work with any protocol
driver having these two methods.
