/**
 * @assertion Stream<FileSystemEntity> list({
 *  bool recursive: false,
 *  bool followLinks: true
 *  })
 * Lists the sub-directories and files of this Directory. Optionally recurses
 * into sub-directories.
 *
 * 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.
 * @description Checks that this method lists the sub-directories and files of
 * this Directory
