/****************************************************
	Ed Yakabosky	CSE 120		Section 002
	This is the final project for CSE 120.
	In this program, a file of holidays and a file of
		magicians is read in, and a user inputs
		individual appointments for customers by
		holiday - and a magician is automatically
		assigned.  If a holiday is fully booked,
		the customer is added to a waitlist.  Users
		can also cancel appointments, add magicians,
		removed magicians, and check the status of
		each item - and the appropriate allocations
		are always made.
	input: magicians.txt, holidays.txt, schedule.txt, 
		user prompts.
	output: 1: schedule, 2: CancelAppt, 3: NewMagician,
		4: DelMagician, 5: Schedule checks, 6: Quit,
		schedule.txt, logfile.txt
