[Dune] arithmetic operators for FieldVector<K,1>

[Carsten Graeser]

Hello Christian,
without the operators my code works for FieldVector<double,1>.
The only point I can see is, that the operator only use '+=' and
not '+' of K. So if you use a type K that does not implement '+' in the
present version FieldVector<K,1> has operator '+'. But K is assumed
to be compatible with double and why should FieldVector<K,1> have '+'
if K has not ?

Does anyone know another reason to have these operators ?
