perlin_zoom	Used to select "zoom" level into the perlin noise, higher numbers result in slower transitions
possible_biomes	2D list of all biomes based on heat and humidity combos. Associative by `BIOME_X_HEAT` and then by `BIOME_X_HUMIDITY` (i.e. `possible_biomes[BIOME_LOW_HEAT][BIOME_LOWMEDIUM_HUMIDITY]`). Check /datum/map_generator/cave_generator/jungle for an example of how to set it up properly.
shared_seed	Should all generators on the same z level use the same seeds?
smoothing_iterations	Amount of smoothing iterations
string_gen	Unique ID for this spawner
weighted_closed_turf_types	Weighted list of the types that spawns if the turf is closed
weighted_feature_spawn_list	Weighted list of extra features that can spawn in the area, such as geysers.

weighted_mob_spawn_list	Weighted list of mobs that can spawn in the area.
weighted_open_turf_types	Weighted list of the types that spawns if the turf is open
Procs
generate_terrain_with_biomes	This proc handles including biomes in the cave generation. This is slower than `generate_terrain()`, so please use it only if you actually need biomes.
populate_terrain_with_biomes	This handles the population of terrain with biomes. Should only be called by `populate_terrain()`, if you find yourself calling this, you're probably not doing it right.

Proc Details

proc
generate_terrain_with_biomes
(/list/turf/turfs, /area/generate_in)

This proc handles including biomes in the cave generation. This is slower than generate_terrain(), so please use it only if you actually need biomes.

This should only be called by generate_terrain(), if you have to call this, you're probably doing something wrong.

proc
populate_terrain_with_biomes
(/list/turfs, /area/generate_in)

This handles the population of terrain with biomes. Should only be called by populate_terrain(), if you find yourself calling this, you're probably not doing it right.

This proc won't do anything if the area we're trying to generate in does not have FLORA_ALLOWED or MOB_SPAWN_ALLOWED in its area_flags.
