This is a stripped down program which draws a picture
using direct pixel modification.  To compile the program
use the command 

javac *.java

If your computer doesn't recognize this command, then 
you have to figure out how to install and/or access
your java compiler.

To run the program, use the command 

java main

You can read the files which have the names [filename].java.
I have a number of comments in these files which try to
explain how the various parts function.
