//  PURPOSE
//	This is a console, command line based Multimedia Organizer.  It reads in, organizes and
//	reports data on various media owned by different persons.
//
//	On my honor:
//
//	-	I have not discussed the C++ language code in my program with anyone other than my
//		instructor or the teaching assistants assigned to this course.
//	-	I have not used C++ language code obtained from another student, or any other 
//		unauthorized source, either modified or unmodified. 
//	-	If any C++ language code or documentation used in my program was obtained from another 
//		source, such as a textbook or course notes, that has been clearly noted with a proper
//		citation in the comments of my program.
//	-	I have not designed this program in such a way as to defeat or interfere with the normal 
//		operation of the Curator System.
