I finally cracked day 8.

I decided to use NumPy for it's multi-dimensional arrays. This was wise *and* foolish. Wise because that's what NumPy is for; foolish because I've never used NumPy.

It turns out that keeping the scaffold of a multi-dimensional array in your head while trying to figure out how to loop across it is pretty demanding. #AdventOfCode
