/*
CavesV6 is the original version of caves used with Mapgen V6.
Though it uses the same fundamental algorithm as CavesRandomWalk, it is made
separate to preserve the exact sequence of PseudoRandom calls - any change
to this ordering results in the output being radically different.
Because caves in Mapgen V6 are responsible for a large portion of the basic
terrain shape, modifying this will break our contract of reverse
compatibility for a 'stable' mapgen such as V6.
tl;dr,
