/*Millersville University Faculty Scheduler System
  Written by:  Joye E. Mills and Dawn White, Fall 1996
  Purpose:  This java applet has been written to allow the MU Faculty to:
		(a) Input their schedule for a given semester
		(b) Update their schedule
		(c) Show all faculty members schedules
		(d) Show a particular faculty member's schedule
		(e) Show all the available times and days that any N number
		    of faculty members can meet
		(f) Notify the parties of the meeting request by e-mail
