The Amazing Double-Ended SPAM Cruncher Applet!
By: Aaron Bernard for CS 60, Section 5, Professor Keller
Code implements the first 2 extra-credit problems.  
1) The head and body of the spam have different colors.  
2) Spam can be added or removedat any time to the grid by 
simply clicking on a square, when paused or while running.
Code is known to work with AWT 1.0 in Mozilla 1.1 and IE 6
on a Windows 2000 platform. Uses verdana font so applet may
generate java console FontExceptions on UNIX platforms.
Note: My coordinate system is row-column based, not
column-row based so the x and y axis is inverted.
