/*
* based on Facebox by Chris Wanstrath -- http://famspam.com/facebox
* 
* :: ported to the Prototype JS library by ::
* Phil Burrows
* http://blog.philburrows.com
* peburrows@gmail.com
* Date: 3 May 2008
*
* Usage:
*  
* This Prototype version is setup to automatically run when the window's load event is fired (see last three lines of this file),
* so usage is as easy as adding rel="facebox" to any link you want to use Facebox
*
* AGAIN, kudos to to Chris Wanstrath and the guys from ErrFree for really putting in the brunt of the effort exerted on this
* I just spent an evening taking all their work and molding it into something that would use Prototype
