Add br sudocode of neighbor finding algorithm

Broken because it's not using a provided Queue like I thought, so I have
to actually link it up with an implemented version. And I'm too tired
for that right now.
Add many more vertices and randomized edges
Create/populate main graph strucure in Gameboard

I'm correctly wrapping around the edges of the gameboard to get the
other end of the row/column. I also just realized I don't actually need
this behavior for this game. Cool achievement, but I'll actually remove
the wrapping to get appropriate connectivity.
Make graph directed again.
Stop wrapping to find neighbors
All spots have vertices attached to eachother!

It even popped out as square rotated 45 degrees, just like the real
gameboard. That's wonderful.
Smaller graph size to test with
Create correct number of vertices for board
Successfully color neighbors of particular spot

Unfortunately I can only flip between 2 colors currently, I'm not sure
how to specify multiple values or a continuous gradient between the 2
colors I provide.
