sim.Cs as default (quite major change)

After long discussion among MZ airflow modellers it was proposed to use sim.Cs as default value for all surfaces also in the 2-port implementation.

I included an override in the siminfomanager  and outer surfaces to go back to the variable Cs implementation in combination with 2-port.
