This is necessary for the upwind scheme in facet coupling models, as
the upwind/downwind volume variables type can be from the other domain.

The code in the implementation is basically just a copy
of the ccexplicitlocalassembler. The only difference is
how the current solution is obtained.
TODO: can we reuse code here?

This function is basically just a forward to evalLocalResidual() and
obtaining the first entry. Since this entire header only deals with
cc schemes we can also write out this call in the occurrences. This
is actually also how we do it in the standard cc local assembler.
