Updated custom library.
...
This includes removing all of the grid-related functions.
I think they need to be rethunk, since I keep inconsistently using
either (x, y) or (r, c) as coordinates, and those are swapped.
Coordinates should probably also be some sort of position struct.
If I need that old code, I can always just look at last year's library.
