* Convert and add cells from an descending connectivity mesh to a nodal mesh.
*
* If the optional filter list extr_cells[] argument is non-NULL, cells
* {extr_cells[0], extr_cells[1], extr_cells[n_extr_cells - 1]} are converted
* and added to the nodal mesh. If this filter is set to NULL, cells
* {1, 2, ..., n_extr_cells} are considered.
*
* In addition, an optional parent_cell_num[] array may also be given, in
* case the descending connectivity mesh definition is based on a temporary
* subset of a parent mesh, (corresponding to the parent_cell_num[] list,
* using 1 to n numbering), and the final nodal mesh element parent numbering
* should correspond to that parent mesh and not the temporary subset.
*
* parameters:
* this_nodal <-> nodal mesh structure
* n_extr_cells <-- count of cells to add
* extr_cells <-- optional filter list of cells to extract (1 to n)
* n_face_lists <-- number of face lists
* face_list_shift <-- face list to common number index shifts;
* size: n_face_lists
* face_vertex_idx <-- face -> vertex indexes (per face list)
* face_vertex_num <-- face -> vertex numbers (per face list)
* cell_face_idx <-- cell -> face indexes (1 to n)
* cell_face_num <-- cell -> face numbers (1 to n)
* parent_cell_num <-- cell -> parent cell number (1 to n) if non-trivial
* (i.e. if cell definitions correspond to a subset
* of the parent mesh), NULL otherwise.
* cell_face_list --> numbers of faces defining polyhedra
