Set U value for layered glasses

[agonzalezesteve]

I'm using the measure Create Baseline Building with standard 90.1-2010, building type Large Hotel and climate zone 3C.

The measure adds this construction.

But when model_add_construction is called, this construction isFenestration but isn't SimpleGlazing because has 2 glasses and air as layers. Then construction_set_u_value is called but as it isn't Fenestration the method returns "Can only set the u-value of opaque constructions or simple glazing" and the U value doesn't change.
