10x10 Drawing Grid

####
# Author: Zachary Williams
# Written in Java using the Processing framework
# Purpose: The program takes a 600 x 600 canvas and makes it a 10x10 grid.
#          You can provide coordinate pairs in blx (block x) and bly (block y).
#          And the program will rectangles and then fill them in so you can draw shapes or designs.
