/**
* Produces a new collection of values by mapping each value in `coll` through
* the `iteratee` function. The `iteratee` is called with an item from `coll`
* and a callback for when it has finished processing. Each of these callback
* takes 2 arguments: an `error`, and the transformed item from `coll`. If
* `iteratee` passes an error to its callback, the main `callback` (for the
* `map` function) is immediately called with the error.
*
* Note, that 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 results array will be in the same order as the
* original `coll`.
*
* If `map` is passed an Object, the results will be an Array. The results
* 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 the transformed item.
* Invoked with (item, callback).
* @param {Function} [callback] - A callback which is called when all `iteratee`
* functions have finished, or an error occurs. Results is an Array of the
* transformed items from the `coll`. Invoked with (err, results).
* @example
*
* async.map(['file1','file2','file3'], fs.stat, function(err, results) {
* // results is now an array of stats for each file
* });
