/*	Project 2 for CS 1704, Spring 2004
	
	Programmer:		John Christopher Humphreys
	OS:				Windows XP Professional
	System:			Pentium M, 512 MB
	Compiler:		Microsoft Visual Studio.net 2003
	Last Modified:	February 14, 2004

	Purpose-
	This program will store student data and data of certain items in two arrays.  Classes will be
	created to hold and manage data of each kind, and a class will manage the arrays.  Data can be 
	edited, printed, or cleared by the controlling class, and all commands, taken from an input file,
	will be processed and executed.

	Format for Comment Block provided by (http://courses.cs.vt.edu/~cs1704/spring2004/Standards/ProgramHeader.txt)
