callback control - simple way to deal with situations when you have lots of callbacks that need to come back together

	/**
	* count is how many callbacks there are in total
	* after to the function to call when all your callbacks have completed
	* return a function that you should call to create your callbacks,
	* optionally passing an individual callback handler
	*/
	function cbcontrol(count, after) {
	return function(cb) {
	return function() {
	cb && cb.apply(this, arguments);
