The index rn_bit at an internal node n represents a bit * position to be tested. The tree is arranged so that all descendants * of a node n have keys whose bits all agree up to position rn_bit - 1. * (We say the index of n is rn_bit.) * * There is at least one descendant which has a one bit at position rn_bit, * and at least one with a zero there. * * A route is determined by a pair of key and mask.
