+Implements the connection manager singleton. The connection manager is a 
+container class responsible for loading, storing, and managing 
+@see CMTPTransportPlugin instances. The connection manager uses the ECOM 
+framework to load and unload transport plug-ins on demand. 
+
+The connection manager is not responsible for controlling or scheduling 
+transport connections, but is notified by the loaded transport plug-ins as 
+@see MMTPTransportConnection instances are created. At which time it will 
+create and bind a new @see CMTPConnection instance to the 
+@see MMTPTransportConnection instance being registered.
