    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.
