[Dune] fem and the indesets

[Christian Engwer]

Hi,

after I got the autobuilder working again I wanted to reduce the
errors (at least for sgrid and yaspgrid). During my investigation I
found out that sgrid doesn't work in the new fem stuff, because this
fem stuff expect some enums/methods to be in the sgridindexset:

1) fem/lagrangebase/lagrangemapper.hh:156: error: `ncodim' is not a member of `Dune::IndexSet<Dune::SGrid<2, 2>, Dune::SGridLevelIndexSet<Dune::SGrid<2, 2> > >'
2) dune/fem/dofmanager.hh:584: error: 'class Dune::IndexSet<Dune::SGrid<2, 2>, Dune::SGridLevelIndexSet<Dune::SGrid<2, 2> > >' has no member named 'insertNewIndex'
3) dune/fem/dofmanager.hh:565: error: 'class Dune::IndexSet<Dune::SGrid<2, 2>, Dune::SGridLevelIndexSet<Dune::SGrid<2, 2> > >' has no member named 'removeOldIndex'

-> 1) shouldn't this information be clear? ncodim == dim ?!
-> 2/3) these methods aren't part of the interface what are they
		supposed to do? The grid is responsible for changing the
		IndexSets?!
