Created July 7, 2015 01:36

A function that replicates the familiar javascript fallback functionality for jquery objects (which are truthy).

	var fallback = function(options){
	var numOfOptions = options.length;
	if (numOfOptions == 2){
	return (options[0].length > 0)? options[0] : options[1];
	}else if (numOfOptions > 2){
	return fallback(options.slice(1));
	}else if (numOfOptions == 1){
	return options[0];
	}else{
	return $();

	# Example: do stuff over the next 30+ mins that requires sudo here or there.
	function wait() {
