*使用方法：一般是直接在文档类初始化一个静态对象，比如定义为Main.soundManage
*添加一个声音：Main.soundManage.addSound(声音id,声音url地址);//通过id访问管理器中的声音
*添加并播放一个声音：Main.soundManage.addAndPlaySound(声音id,声音url地址,循环次数);//如果需要一直播放背景音，建议把循环次数设置为int.MAX_VALUE
*播放指定声音：Main.soundManage.play(声音id,循环次数);//默认为播放一次
*停止指定声音：Main.soundManage.stop(声音id);
*获得指定声音的Sound对象：Main.soundManage.getSound(声音id);
*获得指定声音的SoundChannel对象：Main.soundManage.getSoundChannel(声音id);
*移除指定声音：Main.soundManage.removeSound(声音id);
*设置音量大小：Main.soundManage.setVolume(声音大小);//0静音~1最大
*停止播放所有声音：Main.soundManage.stopAllSound();

一般游戏这个管理器就够用了 如果不够可以在上面继续改进~
