To do that, I want to mirror some of the class structure in the reduced order setting. I would like to start with the UnsteadySystem class, since there the time-stepping takes place. Now I am not so familiar with this factory pattern scheme. What would I need to do to have a, say UnsteadySystem_ReducedOrder class, which (for a start) does the same as the UnsteadySystem class and can be called with a different EQTYPE identifier in the session file? I want to use it for UnsteadyNavierStokes, the incompressible case.
