Remove deprecated support for Prebasis without indices method
This MR removes support for PreBasis
implementations not providing PreBasis::indices
from the PreBasis
concept and the DefaultLocalView
and DefaultGlobalBasis
implementations. As a consequence it also removes support for the old NodeIndexSet
interface from those classes. Furthermore it removes the backward compatibility implementation of PreBasis::IndexSet
and PreBasis::makeIndexSet
from all PreBasis
implementations.
All of this has been deprecated in 2.8 and can now safely be removed.
