Chapter 2: Drawing Basic Shapes.

In this chapter we will be getting graphical. You will learn how to draw
rectangles, circles, lines and points of various colors. These programs will get
more and more complex, so you will also learn how to save your programs to
long term storage and how to load them back in so you can run them again
or change them.

Drawing Rectangles and Circles:

Let's start the graphics off by writing a graphical program that will draw a
traffic light, specifically a green light.
