[Dune] Prospects of VariableBCRSMatrix

I would like to have such feature too.

If you want, we can join forces on such a project. As Oliver mentioned,
I suppose it's doable if one does not try to mimic BCRSMatrix's
implementation too much, as Oliver already mentioned.

So, if you would like to work together on this feel free to contact me.

Best,
Lasse
