Maze Solver - Half Size

The half size micromouse maze solving contest is a development of the classic contest. The rules are almost identical except that the dimensions of each cell are half that of the classic contest. The maze is now 32 x 32 cells and the goal may be any rectangular region that will be specified in advance.
