  const Dune::GenericReferenceElement<ctype, dim> &refelem =
    Dune::GenericReferenceElements<ctype, dim>::general(elemit->type());
  nNodePerEntity = refelem.size(codimofnode);

Note that the first GenericReferenceElement (the element itself) is without an
's' at the end, while the second GenericReferenceElements (the reference
element factory) has a trailing 's'.

Bye,
Jö.
