| * Applies `iteratee` to each item in `coll`, concatenating the results. Returns |

| * @param {Array|Iterable|AsyncIterable|Object} coll - A collection to iterate over. |
| * @param {AsyncFunction} iteratee - A function to apply to each item in `coll`, |
| * which should use an array as its result. Invoked with (item, callback). |
| * @param {Function} [callback] - A callback which is called after all the |
| * `iteratee` functions have finished, or an error occurs. Results is an array |
| * containing the concatenated results of the `iteratee` function. Invoked with |
| * (err, results). |
| * @returns A Promise, if no callback is passed |
| * @example |
| * |
| * async.concat(['dir1','dir2','dir3'], fs.readdir, function(err, files) { |
| * // files is now a list of filenames that exist in the 3 directories |
