my first foray into cellular automata

by default this program runs a single ant on a hex grid under rule: R1R2NUR2R1L2 however, it can easily be configured to run any other rule on a hexagonal grid.
press a to spawn in another ant
press p to pause (if you want to take a screenshot or something) press r to clear the screen and create a new hex grid of random size define a custom rule by changing line #18 in main.lua
make it go much faster by changing repN(tick, 1) to repN(tick, 20) on line 100
