While most operations only need the topology information in the DMPLEX, we must sometimes have the user specify a polytope. For instance, when interpolating from a cell-vertex mesh, the type of polytope can be ambiguous. Also, DMPLEX allows different symmetries of a prism cell with the same constituent points. Normally these types are automatically inferred and the user does not specify them.
