Wraps all global statements and functions into a single self-executing function, replacing global identifier references with local ones. The longer the code, the more complex the generated local references become.

Without Code Transposition:

function logit(){
}
function mylogic(){
	logit()
}

With Code Transposition:

var logit,mylogic;
(function(){
	function a(){
	}
	function b(){
		a()
	}
	logit=a;mylogic=b;
})()
