Surrounded!

Archers on all sides...

It helps to be able to see more than one Space in advance. explorer can now look to get an array of up to 3 Spaces. It will default to 3 Spaces ahead, but it can can also take a Direction parameter:

Space[] back = explorer.look(Direction.LEFT);
Space[] ahead = explorer.look(Direction.RIGHT);

In fact, the methods walk, getSpace, look and poke can each take in a direction parameter (either Direction.RIGHT or Direction.LEFT). If no Direction is passed in, they will default to Direction.RIGHT.
