// Level:
// A refinement level includes a vectorized representation of the topology
// for a particular subdivision level. The topology is "complete" in that any
// level can be used as the base level of another subdivision hierarchy and can
// be considered a complete mesh independent of its ancestors. It currently
// does contain a "depth" member -- as some inferences can then be made about
// the topology (i.e. all quads or all tris if not level 0).
//
// This class is intended for private use within the library. There are still
// opportunities to specialize levels -- e.g. those supporting N-sided faces vs
// those that are purely quads or tris -- so we prefer to insulate it from public
// access.
//
// The representation of topology here is to store six topological relationships
// in tables of integers. Each is stored in its own array(s) so the result is
// a SOA representation of the topology. The six relations are:
//
// - face-verts: vertices incident/comprising a face
// - face-edges: edges incident a face
// - edge-verts: vertices incident/comprising an edge
// - edge-faces: faces incident an edge
// - vert-faces: faces incident a vertex
// - vert-edges: edges incident a vertex
//
// There is some redundancy here but the intent is not that this be a minimal
// representation, the intent is that it be amenable to refinement. Classes in
// the Far layer essentially store 5 of these 6 in a permuted form -- we add
// the face-edges here to simplify refinement.
