A new datastore interface is needed for buffering incoming distributed query results to be sent to the client. This PR attempts to define and implement that interface. It is intended that the ReadChannel() method be used by the goroutine that will push query results down a websocket to the client. Passing the results through this channel will allow that goroutine to perform a select on both the channel and the websocket, in order to properly handle IO.
