-fixed height and moved up or down by 2d perlin noise.
-
-In every layer there can be multiple veins. Veins are blob-shaped volumes 
-of different rocks. Borders of vein are defined by 3d perlin noise. Veins 
-often contain ores.
-
-In every vein, ores are distributed randomly. Some ores 
-may occur in specific areas of the vein (where noise is higher than 
-treshold) or distributed randomly in specific amount (chance based on 
-pseudorandom number) or combination of both.
-
-There is 1 2d perlin noise per layer, 1 3d perlin noise per vein and 1 
-pseudorandom number generator per ore.

-Modding Interface
------------------
-
-"Rocks" exposes api to add new ores, veins and layers. The api is defined 
-in [register](register.lua).
-
-### Register layer
-
-	rocks.register_layer=function(name,params,rock)
-
-
-This function registers a layer. Layer is identified by unique string name. 
-Location of layer is specified in params and node, the layer should be 
-composed of is defined by rock.
-
-Field "params.gain" sets how height of the layer should vary. Field 
-"params.height" sets height of bottom of the layer. Field "params.limit" is 
-value of noise above which the layer is not generated. Set to 2 to disable 
-this feature. Last field "params.seed" is offset to world seed to seed the 
-noise.
-
-### Register vein
-
-	rocks.register_vein=function(name,params)
-
-This function registers a vein with name "name" to be generated according 
-to params.
-
-Field "params.spread" {x,y,z} defines how the vein should look like. X 
-shoudd be equal to z. If y=x=z then the vein is equal in all directions. To 
-make the vein taller, set y to higher value. Larger values make larger and 
-less frequent veins.
-
-Field "params.treshold" specifies rarity of the vein. It should be betveen 
--2 and +2, mapgen will use this or per-ore treshold if per-ore treshold is 
-larger.
-
-- 2 never generate
-- 1 extremly rare
-- 0 50% chance
-- less than 0 = SPAM
-
-Field "params.seed" is added to world seed to form seed for noise function.
-
-Depths, where the wein should generate can be controlled by fields hmin and 
-hmax. They can be set to nil to generate everywhere.
-
-Layers, where the vein should generate in must be listed in Field 
-"params.layer".
-
-## Register ore
-
-	rocks.register_ore=function( vein, node, params )
-
-This function registers ore or rock to be generated in vein "vein". Node to 
-be generated is "node". Params specify parameters, where the rock should 
-spawn.
-
-If noise is larger than Params.treshold, the ore is spawned (set to 2 to 
-spawn everywhere in the vein, 0.8=only in middle). Params.chance specify 
-the chance (/100%) of ore being spawned (0=never 1=always 0.5=50%).
-
-If multiple ores pass the treshhold and chance tests, ore with highest 
-treshold and smallest chance is spawned.
