Discuss a new home for the qto:SlabAspect:SlabDirection property.

[diegoalexdiaz]

We're aiming at deprecating the class "SlabAspect" in the QuantityTakeoffsAspects schema (qto). It contains two properties: "SlabDirection" and "Type". The latter will be replaced by the introduction of a "SlabType" class in StructuralPhysical.

As far as the former, the StructuralPhysical team (where the official "Slab" class is defined) needs to discuss whether the "SlabDirection" property needs to be captured as an aligned/standard concept in such schema, or not.
