- I/O works as far as making pulses show up on GPIO pins
 - Tested just about every function and they all seem to work so far with a few exceptions
 - Added a few more helpers, like utils.strip.get()

Bugs found and fixed:
	color to bin and hex auto-padding wasn't behaving properly
	sorted out syntax errors and mismatches between my own function calls
	sussed out a number of logical errors as well
		(eg the "sliding" was truncating the list from 32 down to 2*nshifts elements)
