Infinite Paging

[Tb1985]

Hi there!
First of all thank you for your code, it's well done and very useful for the app I'm building.
Anyway one thing is missing which I'm trying to achieve is infinite paging.
In my case I have 5 viewControllers and when you reach the fifth swiping further takes you back to the first, same behaviour when you are on the first and swipe back, you should go to the fifth.
I was thinking about achieve this the UIScrollView's delegates methods:
scrollViewDidEndDragging
scrollViewDidEndScrollingAnimation
scrollViewDidScroll

and the selectedIndex value, but you are using a different method to swipe views and none of my test worked.
Could you please gimme any advice on how to achieve it?

Thanks!
