# Converts the code generated by Mike Swanson's Ai->Canvas Export Plug-In 
# for Illustrator into an expression that stores the draw() function
# in a custom JavaScript array member.

# Storing these vector drawing instructions in an array gives me options
# for calling them sequentially in an animation.
