            Tailor action set behaviour

            We first make a few additional cells skeleton cells. The rationale
            behind additional skeletons is given in the @ref benchmarks_exahype2_ccz4_single_black_hole "generic overview".
            Given the first remark there on FD4-FV coupling, one would be tempted
            to use the predicate

            ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
            self._action_set_update_cell.additional_skeleton_guard = " " "(
      repositories::instanceOf" " " + self._name_without_FD4_extension + " " "_FV.isCellOverlappingWithBHImpactArea(marker)
      and
      not repositories::instanceOf" " " + self._name_without_FD4_extension + " " "_FV.areAllFaceConnectedCellsOverlappingWithBHImpactArea(marker)
    )
    " " "
            ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

            Once we study the other items (notably the fourth), we see that it is
            reasonable to make all the overlap region a skeleton within the FD4
            solver.
