-* 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.
