A simple I/O python program with a while loop.

fav_color.py

"""
	A simple program asking a user to guess the "computer's" favorite color.
	The favorite color of the computer is set in a variable, favColor.
	The computer checks the user's input to match the favColor variable.
	If it is any color other than the computer's favorite color, the loop continues.
	Otherwise, the loop is ended when the flag is set to False (or, the user enters the
	exact string equal to the favColor variable.
	
	This will be a given program that students in Game Design will execute. Once executed, they
	will be prompted with a challenge to create their own program which models the concepts in
	the fav_color program.
	
	Objectives:
			handling user input
			variables review
			conditions statements/blocks
			while loop
			stopping a loop w/ a  variable
