Some semi-random thoughts on terrain generation

[xoft]

VillageGridSize is the average distance between village centers, in blocks (supposing the theoretical case that the villages always generate, which is not true due to biomes).
VillageMinDensity and VillageMaxDensity specify the min / max density - that is, how many houses per road. Each village chooses a density from this range and uses it. Values range from 0 (no houses) to 100 (all possible houses)
