程序目的：
输入一个任意大小的迷宫，用栈求出一条走出迷宫的路径，并
显示在屏幕上。
程序实现：
可以实现载入迷宫和保存迷宫，附带文件中有4个测试迷宫路径的
文件test1~4.dd。请将这些文件拷贝到TC当前目录下，或者在载
入时写明完全路径。由于屏幕大小的限制，当用户自己输入迷宫
时一定要注重：迷宫大小是有限制的，不小于4*3,不大于30*20。
否则会出现错误信息。输入开始时全是墙，用上下左右键移动，
用Del键删除墙，形成通路，用Enter键添加墙。输入结束时可以
将迷宫保存下来，以dd为扩展名。输入完毕时用F9键来得到结果，
找到路径时，屏幕下方会出现Path found，否则出现Path not found。
程序经Turbo C 2.0编译调试成功。运行时不用添加任何运行库。
不可以在VC上编译。
