+ * @static

+ * @category Collection
+ * @param {Array|Object|string} collection The collection to iterate over.
+ * @param {...(string|string[])} props The property names to sort by,
+ *  specified as individual property names or arrays of property names.
+ * @returns {Array} Returns the new sorted array.
+ * @example
+ *
+ * var users = [
+ *   { 'user': 'barney', 'age': 36 },
+ *   { 'user': 'fred',   'age': 40 },
+ *   { 'user': 'barney', 'age': 26 },

+ * _.map(_.sortByAll(users, ['user', 'age']), _.values);
