   * @brief An item for a Tree model/view of a file or directory
   * @author Geoffrey Hutchison
   *
   * This class implements a tree item for a model/view of a directory
   * structure. It is used in multiple places for list or tree views
   * for example in the Insert Fragment dialog.
   *
   * In particular, the class contains a non-user visible property
   * which stores the full path to the file it represents on disk.
   * Use filePath() or setFilePath() to access this.
