Extends from BondLib.Interfaces.ActiveOnePort (Partial model invoking one bondgraphic connector).

Information

It would not have been necessary to create a separate roof model, as this model is exactly the same physical model as the exterior wall model (only with different physical parameter values), yet cut and paste is cheap, and since the readability of the higher level models seemed improved by offering a separate roof model, such a model was created.
