To generate a maze, input a width and height (3 or greater), and press generate. Note: Javascript cannot
reliably handle the recursive algorithm past mazes of ~180x180, but it is left unlimited for fun.
To enter a custom input, type in a maze of walls ("1") and empty spaces ("0"). Must be all on one line, with no spaces and a specified height and width. For example, "101101101" generates a straight line down through a 3x3 maze.
