[dune-pdelab] Question on how to use assembleUVProcessor

[Christian Engwer]

Dear Jizhou,

I'm some what confused... are you writing your own assembler? Usually
you only modify your local operators, but this is not possible for the
processor boundaries.

Perhaps you could explain what you are trying to achieve and then we
can discuss in more detail what would be the correct approach... or
perhaps something is missing in PDELab and we can improve the library.
