+* Description:  CVASDBMonitor class is an active object that is a wrapper around 
+*               the RDBNotifier class. Events from RDBNotifier are handled by 
+*               encapsulating them in a CNssVASDBEvent object and passing it to all 
+*               its observers. In addition to the events provided by RDBNotifier, 
+*               CVASDBMonitor also provides additional events when a entry is added,
+*               changed or deleted from the VAS DB. CVASDBMonitor owns the list of 
+*               observers of the VAS DB.
