	Generic interface for map generators.  All mapgens must inherit this class.
	If a feature exposed by a public member pointer is not supported by a
	certain mapgen, it must be set to NULL.

	Apart from makeChunk, getGroundLevelAtPoint, and getSpawnLevelAtPoint, all
	methods can be used by constructing a Mapgen base class and setting the
	appropriate public members (e.g. vm, ndef, and so on).
