/**
 * DrawingLab2
 * Inspired by a lab from Jeff Ondich
 * @author Dave Musicant
 * @version 1.0 10/2/01
 *
 * 0. Create a class called DrawingLab2Main with a method main which creates
 *    a DrawingLab2 objects and calls the method "start".
 * 1. Compile both classes, and run main in DrawingLab2.
 * 2. Read all the methods to see what they do.
 * 3. Try changing the parameters passed to SayHello(). What does DrawLine do?
 * 4. Notice that some of the methods are private. What does this do? Why would
 *    you want to make some methods private?
