* Description:
*   An abstract class being representative of the
*   concrete class which the client wishes to use.
*   It acts as a base, for a real class to provide all the
*   functionality that a client requires.
*   It supplies instantiation & destruction by using
*   the ECom framework, and functional services
*   by using the methods of the actual class.
