   This decorator is used to catch exceptions in Annotators to place them into the blackboard. Mostly useful in
   analysis-engines that have a query-interface which should return a failure back to the action-server caller
   if one of the Annotators yields an exception.

   :param function: The update or compute method of the desired Annotator
   :return: py_trees.Status.FAILURE , if an exception has been catched or found in the Blackboard.
