Detailed Description

A block which contains information about subnodes.

Subnode blocks form a sort of "private NBT" for a node. This class is the root class of that hierarchy, with child classes for the leaf and non-leaf versions of a subnode block.

This hierarchy also models the btree_node structure, inheriting the actual iteration and lookup logic.
