Map files are in ASCII format.

First two lines specify WIDTH, HEIGHT in WalkTile resolution (8x8 pixel)

Next HEIGHT lines (each with WIDTH columns) specify walkable tiles

0 = blocked, 1 = walkable

SparCraft::Position p translates into map WalkTile position (p.x() / 8, p.y() / 8)

Sample 20x10 map with all tiles walkable:

20
10
11111111111111111111
11111111111111111111
11111111111111111111
11111111111111111111
11111111111111111111
11111111111111111111
11111111111111111111
11111111111111111111
11111111111111111111
11111111111111111111

If no map is specified in experiment , default map has size: 

40x22 BuildTile == 160x88 WalkTile == 1280x704

This size was chosen to best fit the Display's 1280*720 pixel size, and is also a decent sized arena

If a GameState contains any initial unit whose Position is on a non-walkable tile, the experiment will not run
