    14 * Description:  This file contains the header file of the MCbsMcnObserver class.
       
    15 *
       
    16 *                MCbsMcnObserver is a mix-in class, which must be implemented
       
    17 *                by a MCN client class. 
       
    18 *
       
    19 *                The sole method of this interface gets called when the MCN state
       
    20 *                changes. This occurs when a MCN message is received from network
       
    21 *                and the cell information relayed by the message differs from 
       
    22 *                the previous cell information.
