Reference implementation does not compile
I'm trying to build the reference implementation (so I can implement the implicit solve for Azzam). However, it appears that after the recent PDE overhaul, the reference implementation wasn't tested?
I've gotten past one compile error I couldn't figure out by removing the time() wrapper, but am now stuck on an error I don't understand since I though time_advance_ref wasn't a member function (even in the updated PDE implementation)
