//  Description : In this module CTAPIAddr class is implemented, Map container of addresses 
//                is created as well. Map container is indexed by dialable address and contains 
//                pointer to ITAddress interface. CTAPIAddr keeps registration number for the
//                address. This number is given when some address are registred to receive 
//                event notification (on ITTAPI::RegisterCallNotifications). We need that for 
//                unregistration (done in destructor).
