X::ElementType	dot (const X &x, const X &y) const
	Dot product of two vectors. It is assumed that the vectors are consistent on the interior+border partition.

template<typename X >
Dune::template FieldTraits< typenameX::ElementType >::real_type	norm (const X &x) const
	Norm of a right-hand side vector. The vector must be consistent on the interior+border partition.
