/**

* ## scatter

* Randomly chooses a location and generates a cluster of ore.

* If noise_params is specified, the ore will be placed if the 3D perlin noise at that point is greater than the noise_threshold, giving the ability to create a non-equal distribution of ore.

*

* ## sheet

* Creates a sheet of ore in a blob shape according to the 2D perlin noise

* described by noise_params and noise_threshold.

* This is essentially an improved version of the so-called "stratus" ore seen in some unofficial mods.

* This sheet consists of vertical columns of uniform randomly distributed height,

* varying between the inclusive range column_height_min and column_height_max.

* If column_height_min is not specified, this parameter defaults to 1.

* If column_height_max is not specified, this parameter defaults to clust_size for reverse compatibility.

* New code should prefer column_height_max.

* The column_midpoint_factor parameter controls the position of the column at which ore eminates from.

* If 1, columns grow upward. If 0, columns grow downward. If 0.5, columns grow equally starting from each direction.

* column_midpoint_factor is a decimal number ranging in value from 0 to 1.

* If this parameter is not specified, the default is 0.5.

* The ore parameters clust_scarcity and clust_num_ores are ignored for this ore type.

*

* ## puff

* Creates a sheet of ore in a cloud-like puff shape

* As with the sheet ore type, the size and shape of puffs are

* described by noise_params and noise_threshold and

* are placed at random vertical positions within the currently generated chunk

* The vertical top and bottom displacement of each puff are

* determined by the noise parameters np_puff_top and np_puff_bottom, respectively.

*

* ## blob

* Creates a deformed sphere of ore according to 3d perlin noise described by noise_params.

* The maximum size of the blob is clust_size, and clust_scarcity has the same meaning as with the scatter type.

*

* ## vein

* Creates veins of ore varying in density by according to the intersection

* of two instances of 3d perlin noise with diffferent seeds,

* both described by noise_params. random_factor varies the influence

* random chance has on placement of an ore inside the vein, which is 1 by default.

*

* Note that modifying this parameter may require adjusting noise_threshold.

* The parameters clust_scarcity, clust_num_ores, and clust_size are ignored by this ore type.

* This ore type is difficult to control since it is sensitive to small changes.

* The following is a decent set of parameters to work from:

* ### WARNING: Use this ore type very sparingly since it is ~200x more computationally expensive than any other ore
