The Explorer faces opposition
Pawns can attack Explorers right near them. You can deal with them the same way as you did with Mines, but they take more pokes to kill.
getSpace()- Returns the next Space on the board.
walk()- Moves the explorer forward (to the right) one Space.
poke()- Pokes the next space, causing damage to any Enemy there.
isEnemy()- returns true if the Space contains an Enemy, and false otherwise.
