+	//		A function that wraps the results of a store query with additional
+	//		methods.
+	// description:
+	//		QueryResults is a basic wrapper that allows for array-like iteration
+	//		over any kind of returned data from a query.  While the simplest store
+	//		will return a plain array of data, other stores may return deferreds or
+	//		promises; this wrapper makes sure that *all* results can be treated
+	//		the same.
+	//
+	//		Additional methods include `forEach`, `filter` and `map`.
+	// results: Array|dojo/promise/Promise
+	//		The result set as an array, or a promise for an array.
+	// returns:
+	//		An array-like object that can be used for iterating over.
+	// example:
+	//		Query a store and iterate over the results.
