Resolves #249 - removes the state monitor runnable from the channel

Browse Source 
state and replaces it with a processing chain heartbeat that is generated
by the sample source.

Previously, the state monitor was running on a separate thread and this
was causing multi-threading issues.  With this update, all channel state
operations (and all module operations) occur on the source's buffer
processing thread.
