Yawnoc reverses Conway's Game of Life.
Well, it tries.

Main has two functions: reverse, and random.

= Reverse =
Load a Conway state from a file, and then use Yawnoc to
find a state C such that C.step() yields the loaded state.
Accuracy is measured as a percentage of the cells that are the same
between the given and the guess.

usage: main.py reverse filename [--color] [--debug]
    filename: data file to load.
    color: use ansi colors in terminal to illustrate progress.
    debug: show Yawnoc board during corroboration phase.


= Random =
Generate a random RxC grid and step() it once. This guarantees we start
with a state that isn't a Garden of Eden. Then, use Yawnoc to guess and
score the results as in Reverse.

usage: main.py random rows columns [--color] [--debug] [-s SEED] [-x CHANCE]
    rows: height of the field
    columns: width of the field
    seed: random seed
    chance: fill percentage. 1.0 is full, 0.0 is empty.
    color: use ansi colors in terminal to illustrate progress.
    debug: show Yawnoc board during corroboration phase.
