* This is the very very early beginnings of an EventQueue:get module.

* This won't function yet as far as the client can tell..  because it doesn't respond to the first query with a 200 message.   
* We have to figure out how to encode those binary values in the example code in the module...  
* Committing this so we have a start point.  Will continue to work on this more today.
