====== About the script ======
  * Purpose : This script will give you a beautiful page transition animation and an optional horizontal page loop
  * Author : [[https://plus.google.com/+LukasMorawietz|LM13]]
  * Current Version : 1.0
  * Link: https://plus.google.com/115366157037831519359/posts/GqZBMeMEpLT
  * Download avialable! (Check repository)

====== Changelog ======
  * Version 1.0 (13/7/2014): initial release in wiki



====== How to use the script ======
  * Set the script to the positionchanged event of your container
  * enable infinte scrolling if you want a page loop, disable it if you don't want to loop through pages
  * in this container: create a shortcut or a gesture to the script 
  * one click on the shortcut will enable the animation, clicking again will disable the animation. 
  * BE SURE TO DISABLE THE ANIMATION BEFORE YOU EDIT, MOVE OR ADD ITEMS!

//please report all bugs in the g+ community!//
