--[[ These biomes try to resemble MC as good as possible. This means especially the floor cover and
the type of plants and structures (shapes might differ). The terrain itself will be of course different
and depends on the mapgen.
Important: MC also takes the terrain into account while MT biomes don't care about the terrain at all
(except height).
MC has many “M” and “Hills” variants, most of which only differ in terrain compared to their original
counterpart.
In MT, any biome can occour in any terrain, so these variants are implied and are therefore
not explicitly implmented in MCL2. “M” variants are only included if they have another unique feature,
such as a different land cover.
In MCL2, MC biomes are usually split in two parts: A land part and an ocean part. Sometimes there's a beach/shore part as well.
The ocean biomes correspond to the MC Ocean biome.
Other intentionally missing biomes:
* River (generated by valleys and v7)
* Some Plateau biomes
* Mesa (Bryce)
TODO:
* Extreme Hills+ M
* Jungle M
* Better beaches (varying height)
Tricky are the beach (esp. stone beach) and mushroom island biomes as they have specific conditions we can't check in MT. :(
TODO: Find a way to position these biomes accordingly.
