/**

This class implements most of the MTM instance management for the SendAs server 

sessions and subsessions.

The SendAs server maintains a single instance of this class, while each session

maintains its own array of available MTMs. The SendAs server also owns a 

CMsvSession object and inherits from MMsvSessionObserver. When notified of a message 

server event affecting MTM availability, the sendas server updates the MTM manager 

and each open sendas session of the change.

CSendAsSession uses this class to provide a default list of MTM's available for

sendas operations. Sessions then update their own available list based on subsequent

RSendAs filter operations.

CSendAsMessage uses this class to obtain instances of MTMs.
