[Dune] Field Vector with K = std::complex<double> ?

[Benedikt Oswald]

Hi Oliver, thanks...but:

when I read the documentation for the method two_norm() it says that it calculates
the square root of the sum of the square of the elements, but for a complex vector
one would require that the method calculates the square root over the sum of
the element times its complex conjugate ?

what do you think on this ? 

Greetings, Benedikt
