+* Description:  This file contains the header file of the MCbsMcnObserver class.
+*
+*                MCbsMcnObserver is a mix-in class, which must be implemented
+*                by a MCN client class. 
+*
+*                The sole method of this interface gets called when the MCN state
+*                changes. This occurs when a MCN message is received from network
+*                and the cell information relayed by the message differs from 
+*                the previous cell information.
