an implementation of allResolved for angularJS

	function allResolved(promises) {
	var deferred = $q.defer(), // our aggregate promise
	counter = 0, // know when to resolve our deferred
	results = []; // where we collect the ordered results of each promise

	angular.forEach(promises, function(promise, key) {
	counter++;
	// might be a value, wrap it up to be safe
