It is theoretically possible to have multiple generator threads by having multiple instances of this object,
but then it MAY happen that the chunk is generated twice.
If the generator queue is overloaded, the generator skips chunks with no clients in them
Generating works by composing several algorithms:
Biome, TerrainHeight, TerrainComposition, Ores, Structures and SmallFoliage
Each algorithm may be chosen from a pool of available algorithms in the same class and combined with others,
