2048 控制台版(C#)

2048游戏现在很火啊，很多人应该已经玩过了。在博客园上也看见有人模仿做的GDI+版 2048游戏，鄙人暂且不做那么多动画的东西，毕竟是个小东东，在此奉上一个《控制台版2048》。

Main 方法程序入口，RePaint 类似Win32程序中的刷新界面，SquareRot90 矩形矩阵顺时针旋转90度角（参数可以为负，表示逆时针）。Merge 向左移动，合并单元格中值相同的元素，并进行整理（将所有元素靠左放置）RandomPoint 随机生成点，从矩阵的空位置（值为0）中随机生成一个点，若不存在空位置返回null。CanMove 判断是否可以继续移动，也是判断游戏是否结束的方法。IsEquals 判断两矩阵的值是否相同。CopyToB 将矩阵复制一份。
