  /**
   * 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
   * });
