Mobile-Touch Module

When you write the touch event, there will always be a variety of bugs, just found Zepto touch module, very useful, and because of Zepto and jquery syntax similarity, this module can be directly referenced to jquery,

It takes time to digest it so that you can do whatever you want ...
