 /** Method paintComponent is called AUTOMATICALLY when needed.
     * The following is general Java stuff, not specific to this project.
     * Rules:
     *   1. Don't call this method directly!
     *      You may call repaint(); if you want the picture redrawn at any time
     *   2. This method should COMPLETELY redraw the ENTIRE image you want
     *          on the panel
     *   3. Don't call ANY graphics methods from any other method in the program,
     *          unless that method is called only as a result of this one
     * Not exactly rules, but still:
     *   1. You probably should not override any other methods of the base class
     *   2. You probably do not want to declare any objects of this class, 
     *      unless you are writing your own GUI.
     *
     * 
     If at any time while working on this project, you feel you need to violate
     * one of those rules, and don't see any way around it -- ask!
