那为啥不直接继承UICollectionViewFlowLayout呢？ #212

我自己写的继承于UICollectionViewFlowLayout，只需要增加columnCount一个属性，针对多组不同列，只需实现一个代理方法

(NSInteger)collectionView:(UICollectionView *)collectionView numberOfColumnsInSection:(NSInteger)section;
而且还兼容了组头，组尾悬浮效果，使用起来和UICollectionViewFlowLayout一模一样
把自己原来的列表换成瀑布流，甚至一行代码都不用写，非常好用

在CHTCollectionViewWaterfallLayout这个源码上，我也实现了悬浮效果，不过有瑕疵，组内items滚动一半超出屏幕header就不悬浮了，大家有没有完美的处理。。。
