#Cellular Automata kata.
##Description
Most of us have probably heard of Conway's Game of Life, but there are other cellular automata that are equally interesting. In fact, there is a group of 256 one-dimensional cellular automata that are quite easy to simulate but still fun to observe.
These CAs have a number of simple "rules" that define system behavior, like "If my neighbors are both active, I am inactive" and the like. The rules are all given numbers, but they're not sequential for historical reasons.
So to simulate these elementary cellular automata, you first need to construct a rule table. This table is a description of the changes that happen in each discreet step of time.
