乞丐版JAVA扫雷

事先声明:本人是一位刚接触Java不久的菜鸟，所以代码写的略显臃肿，敬请谅解！这个扫雷是我在暑假时做的，灵感来源于csdn上某位大神的博客，不过我个人实在不喜欢他的代码实现，于是我自己写了一个实现上不同的扫雷。

这是那位大牛那篇扫雷的博客链接:http://blog.csdn.net/su20145104009/article/details/52152514，有兴趣的可以去浏览下。

程序:主界面上和Windows经典的那款扫雷很像，正上方有一个笑脸按钮，用于游戏重启，下面是雷区，用一个继承于JButton组件的类型实现。笑脸按钮两侧，一侧用JLabel显示剩余雷数，一侧用JLabel显示使用的时间。菜单栏上有难度设置，也是仿制windows经典扫雷的难度设置，即9*9，16*16，30*16三种级别。之所以叫乞丐版主要是左右同时敲击鼠标不能敲开周围的块而且没有排名并且记录的那个功能。

P.S.:用的好端端的edge浏览器TMD崩了，我真他们是CTM，我本来写的一大堆程序解释瞬间消失，算了我还是直接讲最主要算法吧。（这一下弄得我实在是没有热情再写那么详细了，我明明已经快写完了。第一次草稿保存的是如上内容，晚上修改的后面的所有全没了。网页崩了而我的系统屁事儿没有依旧飞快运转。。。。我可是在熬夜写这个啊)

主要难点在于如何判断点击后如何判断九宫格的位置，要引入两个值，edgeU和edgeD(不偏不倚这两个值我还真的给他们起名为edge，看着就来气)，在雷区内总有些位置很尴尬它们周围并没有形成完全的九宫格，不过没有关系。因为在整个区域内只用两条竖边很特殊，它们的前一个或者后一个不一定在它们的左边或者右边，这个时候利用上面那两个值就很管用了，具体怎么用的我不想讲了，请自己去看代码吧(热情实在是被浇灭了。。。)在判断完九宫格内雷数后，你还要展开周围没有雷的地方(被展开的周围如有空位置也要一起展开)，具体实现也请看代码。
