Face planes comparer 

remarks This is intended to sort already known unique PlanarFaces by FaceNormal, so that we can control the order that clip planes are created in. If we do have multiple faces with the same normal, use Origin as a tie-breaker. If we do have mutliple faces with the same normal and origin, the user will have to check for this condition.
