        solved using Upstream:
        (theirs) C(each T(start=292))  vs.  (mine) C(each T(start=TStart)); parameter TStart ...
Every layer in a Construction is instantiated as a MonoLayerOpaque.mo.
Removed conditional instantiation of MonoLayerOpaqueNf.mo (class unnecessary)
Removed double parameter insttantiation
Removed default value for insulationThickness and corrected typo.
Added assert to check if every layer has a thickness larger than zero.
Added fully-filled wall Construction
