object Wall extends Square

The singleton object Wall represents walls, that is, squares that constitute unpassable barriers for robots. A robot can never be in the same location with a wall.

Since all wall locations in all robot worlds are alike and immutable, it is enough to have a single Wall object that can be placed anywhere in any robot world. There is no need for separate instances for each wall square.
