// This example will reset and rebuild the lighting (heightmap, block light,
// skylight) for all chunks in a map.
// Note: If it looks silly to reset the lighting, loading and saving
// all the chunks, just to load and save them again later: it's not.
// If the world lighting is not correct, it must be completely reset
// before rebuilding the light in any chunks. That's just how the
// algorithms work, in order to limit the number of chunks that must
// be loaded at any given time.
