This encodes all the information of a GeometryType as template
parameters. Some remarks on the implementation:
* This may be a solition for using GeometryType's a template paremters
  and is thus a candidate for dune-geometry
* All methods in Dune::GeometryTypes:: have analogouges in
  Dune::Functions::StaticGeometryTypes:: and additional template
  aliases for parametrized types. Hence you can e.g. use Simplex<dim>.
* There is LocalHybridGeometryTypeIndex which works like LocalGeometryTypeIndex
  but supports GeometryType and StaticGeometryType.
* Some topologyIds are different: If you want to overload for specific
  StaticGeometryType's, you must be sure that the same geometry type
  leads to the same type. Hence topologyIds are normalize to have 0
  in the first bit.
* One may consider using uniqueTopologyId = (topologyId >> 1) as
  template parameter instead to get rid of the nasty non-uniqueness.
