+ * Currently, we detect external changes purely by checking file timestamps against the last-sync

  * FUTURE: Whenever we have a 'project file tree model,' we should manipulate that instead of notifying
  * DocumentManager directly. DocumentManager, the tree UI, etc. then all listen to that model for changes.
