+ Sets the algorithm that will be used to generate
+ the mazes. The default is -1, which randomly
+ selects an algorithm for each maze that is gener-
+ ated. Generator 0 is the original one, and works
+ by walking around randomly until we hit a place
+ we've been before, then backtracking and trying a
+ new direction somewhere. Generator 1 picks a ran-
+ dom spot in the maze, then draws a straight wall
+ from that spot in a random direction until it hits
+ another wall (and continues until the maze is com-
+ plete). Generator 2 is based on sets. Initially
+ all cells are in different sets. Then two neigh-
+ boring cells are chosen and if they are in differ-
+ ent sets, their sets are joined. If they were in
+ the same set, a wall is built between them. This
+ continues until the maze is complete.
+
+ All generators generate mazes with a certain
+ 'characteristic'. See if you can spot them!
