Non-affine parametric finite elements #6

Besides affine transformations of reference elements, we should consider also supporting more transformations, like quadratic ones. This would require a more sophisticated geometry layer, that makes use of jacobians of the diffeomorphisms, since they are no longer linear functions with constant derivatives. See LehrFEMpp

It might be smart to store the coordinates of the simplicies then in a different manner. Maybe a geometry object like in LehrFEMpp is a smart move.
