	FPolygroupLayer	FPolygroupLayer represents a polygroup set on a FDynamicMesh3, which supports a "default" group set stored on the mesh, and then N extended group layers stored in the mesh AttributeSet.
	FPolygroupSet	Polygroup sets can be stored in multiple places.
	FPolygroupsGenerator	FPolygroupsGenerator generates (face/tri/poly)groups for an input mesh based on the geometry and attributes of the input mesh.
