-// Interfaces to the cChunkGenerator class representing the thread that generates chunks
-
-/*
-The object takes requests for generating chunks and processes them in a separate thread one by one.
-The requests are not added to the queue if there is already a request with the same coords
-Before generating, the thread checks if the chunk hasn't been already generated.
-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,
-based on user's preferences in the world.ini.
-See http://forum.mc-server.org/showthread.php?tid=409 for details.
