Elem::node_ref, node_ptr, or node_id will get you a reference to,
pointer to, or id() of a node indexed by local node number.

If you're looking specifically for the mapping between local node
numbers on a surface element vs on the interior_parent() then there's
no single API for that, but you can call node_id or node_ptr on one
and then look up the result with local_node or get_node_index on the
other.
