Got the glowing ball to animate inside the grid
Use mouse for navigation and create a Tile class.
SizeX and SizeY for grids, to allow reconfiguration.
Merge in grid-costs and the animation therein.
Remove the unneeded sprite.
Create the full size of the grid onLoad().
Probably doesn't matter but a small performance boost.
Add in a check that only allows a certain subset of moves.
Each tile now has a random value

The values can be 1 through 5
Merge remote-tracking branch 'origin/grid-system' into legal-moves
