Research direct settings object instantiation

[seanpearsonuk]

Research the possibility of code like this:

>>> import ansys.fluent.core as pf
>>> from ansys.fluent.core import viscous, boundary_condition, boundary_conditions, velocity_inlet
>>> solver = pf.launch_fluent()
>>> visc = viscous(solver=solver)
>>> viscous_model = visc.model
>>> viscous_model.get_state()
>>> cold_inlet = boundary_condition(solver=solver, name = "cold-inlet")
>>> cold_inlet.get_state()
>>> cold_inlet2 = velocity_inlet(solver=solver, name = "cold-inlet")
>>> bc_group = boundary_conditions(solver=solver)

We can discuss what is meant here in terms of implementation. The idea is that groups that allow access like boundary_conditions["<name>"] should generate a singular class so that they can be instantiated via the singular name, which is more natural. Note also that the broader name boundary_condition makes senses as the type to use because the zone_type can always be set. Ideally, you want to be able to call set_zone_type() without invalidating the Python object. The other problem is that set_zone_type() is agroupl-level method anyway, so that if you were to call cold_inlet.set_zone_type() you would still have to qualify the call with the name of self.
