RandomRailroadRushHour - a random solver for the Railroad Rush Hour puzzle (http://www.puzzles.com/puzzlesineducation/plans/rushhourguide.pdf ; http://en.wikipedia.org/wiki/Rush_Hour_(board_game) ; ) To use, one creates a RandomRailroadRushHour object and then adds Piece objects via the object's pieces.add(Piece) method. The first object added is assumed to be the goal piece, and the goal piece position is defined via the constructor. A call to randomWalkSolver() initiates a random walk of the state space.
