Adds 'back to top' links to the page and makes a navigation bar stick to the top of the page

jquery.sticky-nav.js

// Create a sticky widget 
	var STICKY = {}
	
	// Start a timer on window scroll to prevent firing lots of extra functions
	STICKY.timer = setTimeout(function(){})
	
	// Only do the following if the browser isn't IE 6
	if(!$('html.ie6')[0]) {
		
		// Add 'back to top' links, except in IE 6
		$('#container')
			.append('<div id="back-to-top"><a href="#">Back to top</a></div>')
			.append('<div id="back-to-top-2"><a href="#">Back to top</a></div>')
		$('#back-to-top').hide()
			.css({
				'top': '0px'
			})
		$('#back-to-top-2').hide()
			.css({
				'bottom': '0px'
			})
		
		// Clone the sticky nav
		$('#sticky-nav').parent().append($('#sticky-nav').clone().attr('id', 'sticky-nav-clone').hide())
		
		$(window).scroll(function(){
			clearTimeout(STICKY.timer)
			STICKY.timer = setTimeout(function(){
				STICKY.makeSticky("#back-to-top")
				STICKY.makeSticky("#sticky-nav-clone")
				STICKY.makeSticky("#back-to-top-2", true)
			}, 50)
		})
