/** Assignment:  Modify this file (previously SimpleApplet5)

 ** In addition, figure out which way (horizontally or 
 ** vertically) the two nested loops in the program are
 ** painting the color boxes, and then change the program
 ** so that it paints the color boxes in the opposite      
 ** direction. Also, edit MyApplet7.html in the  project 
 ** directory, to run the MyApplet7.class file you create,
