//     JQuery Text resize + Cookie recall
//     Ben Hayes, January 2010 | info@jackfruitdesign.com
//     Based initially on a script from http://www.shopdev.co.uk/blog/text-resizing-with-jquery/
//     This script gives a simplified binary option: normal or large text

	     var SMALL  = 11; //small font size in pixels
	     var MEDIUM = 14; //small font size in pixels
		 var LARGE  = 16; //larger size in pixels
	     var COOKIE_NAME = "Simple-Fontresizer"; //Maybe give this the name of your site.

	     //make it small by default
	     var fontsize = SMALL; 

	     // Only show text resizing links if JS is enabled
	     $(".fontresize").show();

	     // if cookie exists set font size to saved value, otherwise create cookie
