          Create a feature gazetteer. This gazetteer processes all annotations of some type in some
          input annotation set and tries to match the value of some feature against the given string
          gazetteer. If a match is found, the action defined through the processing_mode parameter is
          taken. If the annotation does not have the feature or no match occurs, no action is performed.
          The gazetteer uses any instance of StringGazetteer to perform the matches.
