//
//  This JavaScript adds a special effect to your links when clicked.
//  The original "a" html tag does not need to be changed.
//  Links which have a "rel" attribute are not modified, so scripts like LightBox should still work.
//
//  This script uses special effects library from Scriptaculous JS ( http://script.aculo.us )
