- IFC: use smart pointers to keep STEP-SELECT entities in the converted output data structures. This allows us to free the original parameter tuples early as ownership of their members can be transferred. This cuts down memory overhead to 8x (assuming a typical x64 builds) and reduces loading time on average by ~5% as measured on my system.

- Further work on IFC, fix transformations, support non-uniform transformations, optimize loading, use recursive algorithm to resolve holes in polygons, implement CSG logic to generate wall openings. The latter is currently disabled.

- IFC: implement automatic conversion from polygons with holes to polygons that consist of only one piece and are thus applicable to triangulation by ear-cutting. This solves many of the broken windows that would fall victim to z-fighting in earlier revisions.

- IFC: directly keep a pointer to the class name in STEP::Object. This avoid hacking around with typeid().name(), which yields platform-dependent results.
