*	PROJECT #2			< Cd_main.cpp >
*
********************************************************************
*
*	Objective:
*   The program provide the opportunity to demonstrate the following
*		1) A general ability to write and debug a modest size c++ program.
*		2) An understanding of classes and templates
*		3) An understanding of pointers and 
*		4) The implementation of a singly and a doubly linked lists.
*********************************************************************
*
*	This project implement a database to manage a CD club. The program 
*   does this through two linked lists. ths first is a singly linked list 
*	which  contains information on each CD.The second list is a doubly 
*	linked list containinf information on each individual club members.
