-// MineShafts.cpp
-
-// 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
