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

 * results are concatenated as they return. The results array will be returned in
 * the original order of `coll` passed to the `iteratee` function.

 * @method
 * @category Collection
 * @alias flatMap
 * @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
 * });
