edit-along

A collaborative text editor implementing Neil Fraser's differential synchronization algorithm as a Python server with a JS client. The implementation is functionally complete, but does not address all the network failure scenarios considered by Fraser. A caveat is in order: The project was conceived as an experiment in using coroutines/continuations in Python. I haven't had a chance to clean or tighten up the code since.
