+* Description:  CenRepListener listens to given Central Repository setting id and notifies its
+*                observer if there is any change. Observer is given as a parameter on 
+*                initialising the listener. Observer must implement MhspsCenRepObserver-interface.
+*                CenRepListener is asynchronous object that deploys a client-side handle
+*                on Central Repository Server. CenRepListener is intended to be used by any object
+*                that wants listen Central Repository changes.
