[dune-pdelab] ambiguosity in istlsolverbackend.hh

[Bernd Flemisch]

Hey Markus,

yes, it happens when using a PowerGridFunctionSpace with the power one.
We simply always use a PowerGridFunctionSpace, no matter how many
equations we have. The number of equations is passed as a template
parameter and we do not have to change anything more. In this way, we
can use a very general matrix assembler.

Meanwhile, I also noticed that it does not work with parallel UG,
throwing an exception because it is nonoverlapping. That'ok, I just
wanted to try the new pdelab solver stuff, and think it is quite nice...

Kind regards
Bernd
