queue function calling continuous, step friendly, without hanging, but less performance for lot of function calls...

setqueue.global.js

function setQueue(func){
  setQueue.fns.push(func);
  if(!setQueue.isRun){setQueue.isRun=true;setQueue.invoke();}
} setQueue.delay=0;setQueue.fns=[];
setQueue.invoke=function(){
	setTimeout(function(){
		if(!setQueue.fns.length||!setQueue.isRun){setQueue.isRun=false;return;}
		var fn=setQueue.fns.shift();
		if(typeof(fn)=='function') fn();
		setTimeout(arguments.callee,setQueue.delay);
	},setQueue.delay);
};setQueue.pause=function(){setQueue.isRun=false;}
setQueue.clear=function(){setQueue.fns.length=0;}
