//  Project 2 for CS 1704 Spring 2004
//
//  Programmer:    Phil Wallace
//  OS:            Windows XP Professional
//  System:        Pentium 4 2200, 768 MB Memory
//  Compiler:      Visual C++ .NET
//  Last modified: February 22, 2004
//
//  Purpose:
//	The purpose of this program is to implement a crude multimedia organizer
//  using the student, item and storage classes


/*
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.
