Inbox Listener
To receive unicast (point-to-point) messages, listen to a unique inbox subject name. First call TibrvTransport.createInbox() to create the unique inbox name; then call TibrvCmListener() to begin listening. Remember that other programs have no information about an inbox until the listening program uses it as a reply subject in an outbound message.
