In the "Star Wars" rule (352/2/4), there exist structures that
expand infinitely in one dimension (usually at an angle of 45
degrees to the axes) while moving in a direction perpendicular to
their expansion. What is this class of structure called?

Also, here's a small p12 oscillator that showed up while I was
expirimenting with Golly's random fill feature on this rule:

I was unable to find an official list of pattern names for this
rule, so, for now, I'll call this oscillator a "cross with p12
orbitter."

These are the functions for my 22-color encoding of a Deque of
base-10 integers on a TM (I could cut it down to 12, but that would
make it to easy to see the contents of the deque)

Input: The base-10 integer to push, followed by the encoding of
the rest of the initial deque
