Who owns the model? The interface? Or the driver? Both? about funtofem

I'm going to close this issue if that's ok. I gave it the question label so people can search for it later under the question labels section. I have another issue that I intend for people to see in the future after it is closed as well. I wonder what is the best way to ensure that.

Yeah, there is some overlap in providing data from the model class to the SolverInterface class, with the FUNtoFEMmodel in the constructor and the Scenario and Body classes through the initialize, iterate, methods, etc. Also, a better name for the initialize method would probably be initialize_forward as it is the forward analysis version of initialize_adjoint.

Many of the objects in FUNtoFEM need the model in the constructor including all of the SolverInterface classes (as of yet). The Fun3dInterface, for example, needs to know each of the bodies during its construction since it reads in the aero mesh through FUN3D and stores the coordinates in each Body. On the other hand, the TacsSteadyInterface needs the model in the constructor so that it can initialize the ScenarioData metadata class for each Scenario, holding adjoints, functions, and TACS states. Finally, the FUNtoFEMnlbgs driver needs the model so that it can loop over each scenario calling the appropriate analyses from each solver, and telling it which bodies to include in the analysis.
