/*   
	LIGHTBOX for BPC Secure Website                               

	Created By: 	Nick Voss 6/13/08
	
	Usage:  		call load_lightbox_content(load_url) wherever you need to and it will fade out the page and place the
					contents of the url into the box.  Uses ajax to make the load
	
					call lightbox_off() to close the lightbox from another function, or allow the user to click close
			
	Requirements:  	Absolutely needs the prototype framework and the scriptaculous library for the effects.
