代码说明：

Design Pattern 里讲到的Maze类,用于创建型模型,可以一边看书,一边看这里面的代码,加深理解. 代码只是示意,只能Compile,Link不能成功,因为有些函数没有实现.只为学习用的^_^-Design Pattern category referred to in the Maze, used to create models that can read the side, while watching this code inside a deeper understanding. Code is indicative only Compile, Link can not succeed, because some functions did not materialize. Only for the study ^ _ ^
