Lab exercise 2

1.
Make an applet that draws colored filled concentric circles.
Look at CirclesLab.html in the class web site's Labs directory 
for an idea of how it should work.
Use a loop and random Colors (look at FlashingCircles.java).

2.
Then add a JTextField to the applet that takes the user's input and
draws that number of circles.
Use figure 6.16 as a guide to how to create and add a GUI component to
the applet.
