- all include the planar reference from documentation figures
- all include the single polygon case (quad or tri)
- all edge-only cases include semi-sharp boundary vertices
- updated the edge-only and edge-corner shapes consistent with Catmark
- moved the existing triangulated cube to loop_cube_asymmetric
- added new loop_cube with symmetric triangulation and limit surface
- added semi-sharp and inf-sharp variations of cube and icosahedron
- added shapes with extra-ordinary interior and boundary vertices
- added shapes with face-varying features similar to Catmark
