Version 5

This is a trivial change. I pulled out some comments, and added calls to the Canvas method getSize. This might not work for you. If you get a gray area where the Life board should be (instead of blue and white ovals), your browser probably doesn't understand getSize. You need a more modern browser, or you need to view this applet using appletviewer. To see why this is a cool thing to do, run the applet using appletviewer, and change the size of the applet window. Everything is automatically resized to fit.
