/**
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.
