[dune-fem] Lagrange DG extract points

[Andreas Dedner]

Hi.
Everything in dune-fem works with "GridFunctions" anyway. If you don't 
have a grid function to start with
you can either use a DiscreteFunctionAdapter (as used in the test) or a 
LocalFunctionAdapter which I
think is the solution to your problem?

PS: from my point of view we should be removing the LagrangePointSet 
method from the LagrangeSpace
not add it to the other but that's of course open to discussion....
