/**
 * ClickableWindow illustrates the MouseListener interface.
 * 
 * 0. Run the ClickableWindowTester.  Click to your heart's content.
 * 
 * 1. Read the code.  Where does the message that appears on screen come from?
 * How is the message text printed to screen?
 * 
 * 2. What's the difference between keyTyped, keyPressed, and keyReleased?
 * Move the code out of keyTyped and into keyReleased and re-run the program.
 * How does the behavior of the program change?  Now move it to keyPressed.
 * What happens?
 * 
 * 3. Take a look at Sun's documentation on the MouseListener interface.  Experiment
 * with the various required methods (mouseReleased, etc.) to see if you can
 * make them get called.
