+// cChunkGenerator.h
+
+// 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 (if the cChunkPtr is thread-safe)
+// If the generator queue is overloaded, the generator skips chunks with no clients in them
