-// Declares the cBiomeCache class representing a biome source that caches data from the underlying biome source
-
-/*
-This cache works a bit differently than regular caches.
-It first receives the hint of area that it will need to provide.
-The Cache uses several threads to request biomes from the underlying source to fill that area.
-While the area is being filled, requests for biomes may already come, such requests are answered with baLater if no data yet.
