====== About the script ======
  * Purpose : Make all items in a container animate on a figure 8 when scrolling left and right
  * Author : TBog
  * Link: www.google.com/+BogdanTautuTBog

====== How to use the script ======

Still in development, but the main feature will be that everything will be customizable with an internal GUI
Just set the script in the category "Lightning menu" then long-press on any container (panel was tested) and run the script. A dialog will appear that will guide you further.

Known issue: while the script is running if user enters edit mode an error will appear.

====== Script code ======
