And to python interface

Hours later...

Oddly this fixes the error in derivative, but it should have no impact

Temporaries were being returned when autodiff was being used, forceeval should fix it I think

* Add ability to access a single departure term in a multi-fluid model

* Bump version to dev

Problem: compile-time time arguments remapped to runtime arguments, in future the runtime arguments should come after the model
