-- @brief       Javascript code to emulate the iPhone "delete app" animation.
-- @detail      Give elements the class "css3-wiggler" and include this script.  The script will
--              automatically set up the MouseOver and Mouse out to handle the animation.
--              More details: http://StripedCow.com/articles/css3-jquery-iphone-delete-wiggler
--
--              Note: Small issues with handling mouse out, then mouse over when called rapidly.
