+ MapgenBasic is a Mapgen implementation that handles basic functionality
+ the majority of conventional mapgens will probably want to use, but isn't
+ generic enough to be included as part of the base Mapgen class (such as
+ generating biome terrain over terrain node skeletons, generating caves,
+ dungeons, etc.)
+
+ Inherit MapgenBasic instead of Mapgen to add this basic functionality to
+ your mapgen without having to reimplement it. Feel free to override any of
+ these methods if you desire different or more advanced behavior.
+
+ Note that you must still create your own generateTerrain implementation when
+ inheriting MapgenBasic.
