//  Project 2 for CS 1704 Spring 2004
//
//  Programmer:    Michael Tuozzo
//  OS:            Windows XP Professional
//  System:        Mobile Pentium 4, 1.2/2.2 GHz, 512 MB Memory
//  Compiler:      Visual C++ 6.0, Service Pack 4
//  Last modified: February 18, 2004
//
//  Purpose
//  This program maintains a student/multimedia database.  Each student
//	in the database owns a number of multimedia items also stored in
//	the database.  Students and multimedia items can be added and
//	removed from the database.  Print functions are also available.
//
//    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 text book 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.
//
