Missing Type of ThermalBoundary
Created by: gioagu
As of now (v. 0.6), a there is a "IntermediaryFloor" type.
However, "IntermediaryCeiling" is missing.
The distinction is needed when, for example, modelling each ThermalZone explicitly by means of surfaceGeometry.
I would add it to the enumeration list for v. 0.7
