LoD0 doesn't generate VW's between footprints

[tcommandeur]

When generating a model with LoD0 setting the vertical walls between the footprints are not created for OBJ, other formats not tested. This results in the model not to be watertight.

Problem might be in Building.cpp -> get_obj() where for lod==0 the vw's are not taken into account.

Hi Tom, it seems that I have still that issue when generating CityGML models with LoD0 settings?
