[dune-fem] Lumping Quadrature for Lagrange

[Claus-Justus Heine]

Hi,

another question: is there already a "lumping" quadrature for Lagrange 
elements on simplex grids, i.e. a quad rule with weight 1/dim and 
integration points at the vertices of a simplex? Its extremely simple to 
implement, copying the code from dune/fem/quadrature/ but if it is 
already there ... and yes, there are much more efficient ways to 
implement mass-lumping, but ...

Best,

Claus
