 * @method
 * @see [async.mapValues]{@link module:Collections.mapValues}
 * @category Collection
 * @param {Object} obj - A collection to iterate over.
 * @param {AsyncFunction} iteratee - A function to apply to each value and key
 * in `coll`.
 * The iteratee should complete with the transformed value as its result.
 * Invoked with (value, key, callback).
 * @param {Function} [callback] - A callback which is called when all `iteratee`
 * functions have finished, or an error occurs. `result` is a new object consisting
 * of each key from `obj`, with each transformed value on the right-hand side.
 * Invoked with (err, result).
 * @returns {Promise} a promise, if no callback is passed
