//	AUTHOR:		Simon Willison, http://simon.incutio.com/archive/2004/05/26/

//
//	Attaches a function to the window load event. We use this function because
//	addEvent(o,e,f) is not IE Mac compatible. IE Mac only understands window.onload
//	but multiple window.onload declarations will overwrite eachother.
//	
//	EXAMPLE:
//	addLoadEvent(function(){myFunction(variable);});
