Array Shifting (recursion)

array-shifter.js

//	When you have a huge amount of DOM elements!
//	Using an array instead of a loop by 'shifting' the array speeds up the iterations 
//	and setTimeout prevents the browser from locking up.

		for ( var i = 0, l =  nodes.length; i < l; i++ ) {
			elementArray.push( nodes[i] );
