Analytical differentiation with MultiDomain
It seems like the interfaces for analytical differentiation disappeared from the base coupling manager, but are still called from the local assemblers.
We should clean this up and revise the assemble routines for analytical differentiation in the local multidomain assemblers. Also, we should introduce the respective interfaces to the base coupling managers and throw proper error messages.
@timok, didn't you have an implementation for analytical differentiation in the embedded framework? I don't see it anymore...
