[Dune] Some questions on Curvilinear geometry implementation

[Oliver Sander]

There is no curvilinear geometry in dune-localfunctions.  What there is is an
implementation of Lagrangian shape functions (in dune/localfunctions/lagrange).
The formulas for the values and derivatives of those shape functions are pretty
close to what you need for an implementation of a polynomial geometry.
When implementing your polynomial geometry in dune-geometry you can draw inspiration
from those Lagrangian elements, and maybe copy'n'paste some code.
