效果图：
优缺点：
优点：
1.一条曲线完美解决旋转问题
2. 解决了超速的问题，现在速度再快也不会乱了
3.快速停止的时候进行了进度区分，后面的会等前面的停了再停
缺点：
1.停止节奏上会有细微差距，导致音频节奏不好，可以通过其他方式解决
代码结构：
简述：
ScrollElement：控制元素的图片切换，并记录自己是第几个进入Rect的号码
ScrollRect： 负责管理自己的旋转状态、曲线，堆排序等
（堆排序的目的是 单帧没办法判断有多少个元素从底部到达了顶部，这些元素都需要从列表中拿元素值，为了保证数据顺序，需要进行一次排序）
ScrollManager: 管理所有ScrollRect，并且与其他模块接口
代码：
