(0.5, 0.5, 0.5) should be added to the coordinate of the moving item, not the direction of the movement ray.
Added a check to make sure that a collision occurs within the range of a ray. Otherwise a moving item collides with all items on the line that it is moving along. (And could potentially push a robot that is ten spaces away)
Updated variable names for clarity.
Mocked out the drive and used map.move directly, since this is a map test.
Merge branch 'collision_detection' into push_functionality

Conflicts:
	domain/map.js
Mocked out the drive for the other map tests.
