/// Lists the sub-directories and files of this Directory. Optionally recurses

/// If followLinks is false, then any symbolic links found are reported as Link
/// objects, rather than as directories or files, and are not recursed into.
/// If followLinks is true, then working links are reported as directories or
/// files, depending on their type, and links to directories are recursed into.
/// Broken links are reported as Link objects. If a symbolic link makes a loop in
/// the file system, then a recursive listing will not follow a link twice in the
/// same recursive descent, but will report it as a Link the second time it is
/// seen.
/// The result is a stream of FileSystemEntity objects for the directories,
/// files, and links.
