项目名称:贪吃蛇
编译环境：VC2015
<创建时间：2017.1.14>
<创建者:PorYoung>
<最近完成修改：2017.1.15 18:45 
遗留问题:①难度选择(包括撞墙、多个食物、障碍) ②背景更换 ③其他细节

<最近完成修改：2017.1.16 23:29
修改内容：①增加暂停②重玩功能，将图片嵌入exe
遗留问题：①难度选择(包括撞墙、多个食物、障碍) ②背景更换 ③其他细节
<最近修改：2017.1.17 14:14
修改内容：①增加一个难度选择 ②增加一个更换音乐图标和更换地图图标 ③修复暂停、重玩bug
遗留问题：①第三个难度选择 ②速度、长度调整 ③实现计数和计时 
④实现图标点击切换地图和音乐功能 
⑤经典模式碰图片边框不死>
<最近一次完成修改：2017.1.17 19:57 
修改内容：①修复选择难度不进入游戏 ②删除判断游戏状态函数，直接在判断蛇是否死亡函数里进行退出或重玩 ③修复嵌入音乐无法播放 ④修复游戏过程不断闪屏
遗留问题：①速度(难度)变更 ②背景更换 ③计数与计时 ④界面优化
