 <!--************************  CustomOreGen Minecraft Ores Module *********************************
 *
 *   This file contains Presets, Options, and Distributions for the 7 vanilla minecraft ores:
 *       Coal, Iron, Gold, Redstone, Diamond, Lapis Lazuli, and Emerald.
 *
 ***********************************************************************************************-->
 <ConfigSection>
 
     <!--***************************   Options + Symbols   ***********************************
     *
     *   Below are options and symbols for Coal, Iron, Gold, Redstone, Diamond, Lapis Lazuli,
     *   and Emerald.  Each ore has a "type" option corresponding to select which distribution
     *   is used for that ore in the overworld, and 3 mystcraft symbols for selecting
     *   distributions in mystcraft ages.
     *
     *   Each ore also has its own overall "frequency" and "size" multipliers.  These are
     *   provided so people can tweak the rarity of each ore from the options file rather
     *   than having to edit the config directly.

     <!--*****************************   Distributions   *************************************
     *
     *   Below are the actual distributions for the vanilla ores in the overworld and
     *   mystcraft ages.  There are currently 3 types of distribution for each ore:
     *     Layered Veins:
     *       Some form of veins or clusters arranged loosely by height and more common
     *       in affiliated biomes.
     *     Strategic Clouds:
     *       Huge, rare, low-density clouds.  Size and frequency are fairly consistent;
     *       density is varied to reflect ore rarity.  May be surrounded by a scattering
     *       of single blocks as hints to help guide players in.
     *     Vanilla Clusters:
     *       A re-creation of the vanilla ore generation using the StandardGen algorithm.

                         Isolated veins (no motherlodes) that run vertically.  These veins are fairly common, but a challenge to mine because you have to tunnel straight down.
