   * Tests creating multiple revisions of a node and managing attached files.
   *
   * Expected behaviors:
   *  - Adding a new revision will make another entry in the field table, but
   *    the original file will not be duplicated.
   *  - Deleting a revision should not delete the original file if the file
   *    is in use by another revision.
   *  - When the last revision that uses a file is deleted, the original file
   *    should be deleted also.
