[dune-fem] HangingNodesType in spmatrix.hh (or istlmatrix.hh)

[Falk Meyer]

Hi all,

i have a question concerning Hanging Nodes, which I want to deal with when
assembling the system matrix.
Apparently there are functions (e.g. void changingHangingNodes( ...) ) given
to do so - for example when using a SparseRowMatrix/Object (as in
spmatrix.hh).
There a "HangingNodesType" Object is expected, but I can not find any
documentary or hint how such an object should be defined properly and I don't
wanna guess ;)

Perhaps you can help me or tell me where I can find code using this Type? I'm
curious.

Thanks in advance!
