docs: a class decorator for Crontabber Apps.  This decorator will a class a
      _run_proxy method that passes a databsase connection as a context manager
      into the CronApp's run method.  The connection will automatically be closed
      when the ConApp's run method ends.
  
      In order for this dectorator to function properly, it must be used in
      conjunction with previous dectorator, "with_transactional_resource" or
      equivalent.  This decorator depends on the mechanims added by that
      decorator.
