基于winAPI winmm.dll
mciSendString 编写的帮助类功能比较齐全（起码比我现在网上搜的齐全@-@）已经实现的功能 播放 暂停 停止 关闭就不多说了基本功能没啥好说的。
事件：播放完毕通知，时间变化通知，状态变化通知，错误通知
功能：上一首， 下一首 ，指定顺序播放
播放后状态：单曲循环，列表循环，随机播放
里面用到的BearChildren为我个人编写的工具功能如名字一样熊孩子...意思：让这个框架跟熊孩子一样什么都能做 目前还在完善中
目前框架主要是以单机桌面开发编写的一套工具，内容为图像处理，Io，数据等，我希望能有更多的人来帮助我来完善这个框架在日常工作中让开发变的更加方便快捷，
