Selection of advection type in IncNavierStokesSolver through either AdvectionType or EvolutionOperator is confusing
At present we have two approaches to specifying advection: either directly in the solver through the AdvectionType parameter, or in the Driver through the EvolutionOperator (which then sets it in the solver using an AdvectiveType tag to override the AdvectionType parameter).
This is overly confusing and not documented sufficiently.
