+// Author: Anthony Garand
+// Improvements by German M. Bravo (Kronuz) and Ruud Kamphuis (ruudk)

+// Created: 2/14/2011

+// Website: http://labs.anthonygarand.com/sticky
+// Description: Makes an element on the page stick on the screen as you scroll
+// It will only set the 'top' and 'position' of your element, you
+// might need to adjust the width in some cases.
