/** Enumerated Files Routines.
* FileEnumerator allows you to operate on a set of Gio::Files, returning a Gio::FileInfo instance for each file enumerated
* (e.g. Gio::File::enumerate_children() will return a FileEnumerator for each of the children within a directory).
*
* To get the next file's information from a Gio::FileEnumerator, use next_file() or its asynchronous version, next_file_async().
* Note that the asynchronous version will return a list of Gio::FileInfos, whereas the synchronous version will only return the next
* file in the enumerator.
*
* To close a Gio::FileEnumerator, use FileEnumerator::close(), or its asynchronous version, close_async(). Once a FileEnumerator is closed,
* no further actions may be performed on it.
