Detailed Description

template<class Vector>
class Dune::ACFem::UnaryVectorExpression< IdentityOperation, Vector >

This is the only allowed starting point for vector-expressions: here we allow vectors to be wrapped inside the Identity-operation in order to be valid ExpressionTemplates for further operation.

We require that the Dune::FieldTraits give a reasonable result for the components of Vector (but not necessarily for Vector itself). It is illegal to wrap an existing vector-expression into an IdentityOperation.

We need to specialize this for FieldMatrix objects.
