  /**
   * Returns a new object, where each value corresponds to an array of items, from
   * `coll`, that returned the corresponding key. That is, the keys of the object
   * correspond to the values passed to the `iteratee` callback.
   *
   * Note: Since this function applies the `iteratee` to each item in parallel,
   * there is no guarantee that the `iteratee` functions will complete in order.
   * However, the values for each key in the `result` will be in the same order as
   * the original `coll`. For Objects, the values will roughly be in the order of
   * the original Objects' keys (but this can vary across JavaScript engines).

   * @param {Array|Iterable|Object} coll - A collection to iterate over.
   * @param {AsyncFunction} iteratee - An async function to apply to each item in
   * `coll`.
   * The iteratee should complete with a `key` to group the value under.
   * Invoked with (value, callback).
   * @param {Function} [callback] - A callback which is called when all `iteratee`
   * functions have finished, or an error occurs. Result is an `Object` whoses
   * properties are arrays of values which returned the corresponding key.
   * @example
   *
   * async.groupBy(['userId1', 'userId2', 'userId3'], function(userId, callback) {
   *     db.findById(userId, function(err, user) {
   *         if (err) return callback(err);
   *         return callback(null, user.age);
   *     });
   * }, function(err, result) {
   *     // result is object containing the userIds grouped by age
   *     // e.g. { 30: ['userId1', 'userId3'], 42: ['userId2']};
   * });
