//WARNING: DO NOT SUBMIT CODE WHICH USES THIS FUNCTION WITH wait=true; It WILL time out.
//inputs: same as solver, wait true will make you press enter each time
//        you want the maze animation to update, wait false will speed
//        through the maze. The code should be able to be graded with wait = false
//displays: walls are white, dots are black (blend in with background, this
//          a known issue), green S is start, Red E is end, purple is where
//          the function is currently looking at. Blue background is visited == true;
