CP2003 - Tutorial Eight: More GUI Stuff

Some menu items and a dialog box:
- Firstly, complete the last task from last week's tutorial. You should already have a "left" and "right" button to make the circle move, so now you need to add a menu with menu items "go left" and "go right" to do that same thing. Take a look at ExGui3.java for an example of menus.
- Add a help menu which has an "About" menu item. When the user clicks on "About" it should produce a dialog box with a brief message and a small picture. If you need a picture for the dialog, you can use the gold medal chicken.
You're now free to work on your assignment.
