+//	Utility classes derived from sparse array driver that are used to index/access easily into
+//     the leaf(vertex) buffer internal structure of vertex buffer.
+//  Essentially, these are just sparse array drivers (each sparse array is just the array of positions,
+//     normals, tangents, whatever in the video memory), and these classes are just used to initialize them.
