/**
* A relative of [`map`]{@link module:Collections.map}, designed for use with objects.
*
* Produces a new Object by mapping each value of `obj` through the `iteratee`
* function. The `iteratee` is called each `value` and `key` from `obj` and a
* callback for when it has finished processing. Each of these callbacks takes
* two arguments: an `error`, and the transformed item from `obj`. If `iteratee`
* passes an error to its callback, the main `callback` (for the `mapValues`
* function) is immediately called with the error.
*
* Note, the order of the keys in the result is not guaranteed. The keys will
* be roughly in the order they complete, (but this is very engine-specific)

* @param {Object} obj - A collection to iterate over.
* @param {Function} iteratee - A function to apply to each value and key in
* `coll`. The iteratee is passed a `callback(err, transformed)` which must be
* called once it has completed with an error (which can be `null`) and a
* transformed value. 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).

* async.mapValues({

* f2: 'file2',
* f3: 'file3'
* }, function (file, key, callback) {
* fs.stat(file, callback);
* }, function(err, result) {

* // result is now a map of stats for each file, e.g.
2016-10-10 03:43:44 +02:00
* // {
* // f1: [stats for file1],
* // f2: [stats for file2],
* // f3: [stats for file3]
