support code for the Valleys C++ mapgen
https://github.com/duane-r/valleys_c
This mod exists to support the C++ version of Valleys Mapgen for Minetest, written by Duane Robertson as a port of Gael-de-Sailly's lua-based mapgen. (https://github.com/duane-r/minetest/tree/valleys_c)
The goal of the combined project is not to replicate Valleys Mapgen, but to use the remarkable algorithms Gael-de-Sailly created to make a more traditional mapgen, compatible with the standard Minetest systems (such as biomes and decorations).
20151003 Moved the code to a separate repository, since it no longer shares any lua files with the original.
20150922 Copied my working files up. It's a mess.
