新版黄金矿工
作业要求
新版黄金矿工游戏，共有两个界面：主界面与游戏界面
- 主界面：在demo代码基础上完善场景，添加开始按钮（MenuItem），点
击进入游戏界面。 - 游戏界面：两个Layer，StoneLayer锚点位于左下角，坐标设为(0,0)，其上 有一石头精灵，初始坐标为（560，480）；MouseLayer锚点位于左下角， 坐标设为(0,屏幕高度的一半)，其上有一老鼠精灵，初始坐标为（屏幕宽度的 一半，0）。有一个Label，作为shoot按钮。
- 游戏要求：游戏开始后，点击屏幕任意位置，在该位置添加一块奶酪，老鼠 跑到该位置吃掉奶酪；点击shoot按钮，石头发射到老鼠所在的位置，老鼠 跑开，留下钻石。
- 加分项：尝试添加一两个动画
- 作业提交：提交实验报告（文档），Classes（文件夹），Resources（文件 夹）。实验报告要求有截图。

//这个地方巨坑，因为level-sheet.plist文件里面给了不止一个老鼠的动画
//一开始看到老鼠的动画是老鼠和钻石在一起，所以想到先生成老鼠，再生成钻石
//这样的话，发现老鼠是动的，钻石是不动的，不符合要求
//所以把钻石作为老鼠的子类，这样钻石就可以和老鼠一起动
//但是仔细看demo的示例，老鼠是抱着钻石的，而且钻石是覆盖掉肚子的，这是完全不可能的
//因为老鼠是一个层面的，钻石是一个层面的，要么老鼠覆盖钻石，要么钻石覆盖老鼠，
//所以事情的真相只有一个，老鼠抱着钻石本身就是一张图片。。。。。
