automatic save and load, refactor UI to be hide-able and have the option of starting a new map
hexordinates can now be added together (immutable)
Hexordinate knows how to calculate other tile group adjacencies
New strategies for loading and newing a game map: attempt to load, fail over to new. New uses a portal group tile to start.
Move to adding tile groups instead of tiles. Manage a stack of tile groups to pull from.
Set dimensions to fit my table, trigger calls to the new tile group adding.
Convert constructor to take an options hash for injection. Store a listing of all tiles packed with the real game.
Ack, the html and tests for the last few commits (i wrote them first i swear)
