template< typename, typename > class RingList	std::vector	container type for inner rings, for example std::vector, std::list, std::deque
template< typename > class PointAlloc	std::allocator	container-allocator-type, for the points
template< typename > class RingAlloc	std::allocator	container-allocator-type, for the rings
