##介绍 / Introduction
MultiLayerNavigation可以让你轻易地实现类似网易新闻/新浪微博滑动返回的交互效果；

MultiLayerNavigation helps you implemntation the interaction -- 'drag to go back' in a easy way.
The only one thing you need to do is replacing your UINavigationController with the MLNavigation Controller or inheriting from it.
