-WormNestCave generator:
-Caves are generated in "nests" - groups of tunnels generated from a single point.
-For each chunk, all the nests that could intersect it are generated.
-For each nest, first the schematic structure is generated (tunnel from ... to ..., branch, tunnel2 from ... to ...)
-Then each tunnel is randomized by inserting points in between its ends.
-Finally each tunnel is smoothed and Bresenham-3D-ed so that it is a collection of spheres with their centers next to each other.
-When the tunnels are ready, they are simply carved into the chunk, one by one.
-To optimize, each tunnel keeps track of its bounding box, so that it can be skipped for chunks that don't intersect it.
-
-MarbleCaves generator:
-For each voxel a 3D noise function is evaluated, if the value crosses a boundary, the voxel is dug out, otherwise it is kept.
-Problem with this is the amount of CPU work needed for each chunk.
-Also the overall shape of the generated holes is unsatisfactory - there are whole "sheets" of holes in the ground.
-
-DualRidgeCaves generator:
-Instead of evaluating a single noise function, two different noise functions are multiplied. This produces
-regular tunnels instead of sheets. However due to the sheer amount of CPU work needed, the noise functions need to be
-reduced in complexity in order for this generator to be useful, so the caves' shapes are "bubbly" at best.

-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 generator queue is overloaded, the generator skips chunks with no clients in them

-// Implements the cStructGenMineShafts class representing the structure generator for abandoned mineshafts
-
-/*
-Algorithm:
-The cStructGenMineShafts::cMineShaftSystem class is the main controller, which knows what mineshaft
-classes there are and their random weights. It gets asked to produce a new class everytime a connection is to be made.
-The cMineShaft class is a base class for each mineshaft structure.
-Each cMineShaft descendant knows how large it is, how to imprint itself into the chunk data and where to connect to
-other descendants. Its PivotPoint is always a walkable column. Its Direction determines in which direction the structure
-is facing.
-
-The generation starts with the central dirt room, from there corridors, crossings and staircases are added
-in a depth-first processing. Each of the descendants will branch randomly, if not beyond the allowed recursion level
