Proc4_0.8-5z

In this release, many functions related to either handling Mongo collections, or procesing JSON data have been moved to the new mongo package on which this one depends. Note: dependency is on the mongo package, not access to a Mongo server, although some functions and classes do require the mongo server.

1. Added a new MessageQueue class, along with some functions for manipulating the queue (as this was common to EABN and EIEvent.

2. Added new capability for building tables to the Listener classes. Also, captured some of the code for building ListenerSet objects from json configurations.

The test suite is pretty complete for this package, with a few holes for later functions.
