Make a client --> server foundation for OT.

[kingdion]

This was touched on in the flask demo available on this repo and in the PyCon speech. An actual architecture needs to be designed to perform a working version of operational transformation (potentially using the transform function I've designed).

In this relationship, a client and server will have to be created. A client should only talk to one server, and shouldn't worry about other clients. Operations are relayed back and forth between the server, using await states and buffering other operations (likely as a changeset).

Any help toward this is greatly, greatly appreciated.
