Node permutations for proper subcells.

ParentCell and SubCell are connected if every node of SubCell is also a node of ParentCell. However, the connection may be permuted.

Let ParentCell be dimension D and SubCell be dimension dim < D. Let SubCell be connected as subcell Ord with permutation P.

Then ParentCell.node(K) == SubCell.node(J) where:

• SubCellTopology == ParentCellTopology::subcell<dim,Ord>::topology
• K = ParentCellTopology::subcell<dim,Ord,JP>::node
• JP = SubCellTopology::permutation<P,J>::node
• J = SubCellTopology::permutation_inverse<P,JP>::node

The permutation map for P == 0 is required to be identity.
