Add initial prototype

Note that while the cursor supports sync, the main .patrol api does not yet support it.
And yes this code is incredibly messy.

I chose mocha because jest/jasmine has some issues running with generators

This code also requires node 0.11.x to run.
For the sake of clarity, I would love to rename `ch` to something more verbose, perhaps `cursorChannel` ?
