Description:

Sample code is an example on selection with Condition using SelectionOptionsKit.SetConditions
		HPS::SegmentKey ModelSegKey = GetDocument()->GetModel().GetSegmentKey();

		// Create Conditional Named Style
		HPS::PortfolioKey myPortfolio = HPS::Database::CreatePortfolio();

		HPS::NamedStyleDefinition geometry_OFF = myPortfolio.DefineNamedStyle("vis_off", HPS::Database::CreateRootSegment());
		geometry_OFF.GetSource().GetVisibilityControl().SetGeometry(false);

		ModelSegKey.GetPortfolioControl().Push(myPortfolio);
		ModelSegKey.GetStyleControl().PushNamed("vis_off");
		ModelSegKey.GetVisibilityControl().SetFaces(true);

		// Create two subsegment and set a condition on SubSegment1

		HPS::SegmentKey SubSegment1 = ModelSegKey.Subsegment();
		HPS::SegmentKey SubSegment2 = ModelSegKey.Subsegment();

		// setup conditional style on SubSegment1
		SubSegment1.GetStyleControl().SetNamed("vis_off", "c1");

		Point points[8] = { Point(0, 0, 0), Point(3, 0, 0), Point(3, 3, 0), Point(0, 3, 0) };
