 * Enemy Bulk Drops
 * Version 1.00
 * SumRndmDde
 *
 *
 * Yanfly's Extra Enemy Drops Plugin is required.
 * Place this Plugin BELOW YEP_ExtraEnemyDrops.
 *
 *
 * While Yanfly's Extra Enemy Drops adds a lot of features to help customize
 * the drops of Enemies, it lacks a couple of features to support large
 * amount of possible Item drops. Having the possibility for a large amount
 * of Items to drop is a major part of larger-scale RPGs.
 *
 * While it is technically possible to use a lot of the features within this 
 * Plugin without it, they help a lot with making things simplier and easier.
 *
 * 
 * ==========================================================================
 *  Batch Enemy Drop Percentages
 * ==========================================================================
 *
 * Available Enemy Notetags:
 *
 * <Item x1 - x2: y%>
 * <Weapon x1 - x2: y%>
 * <Armor x1 - x2: y%>
 *
 * This sets a batch of Items, Weapons, or Armors to have a y% chance of 
 * dropping.
 *
 *
 * For example:
 *
 * <Item 3 - 20: 50%>
 *
 * Each Item from 3 to 20 has a 50% chance of dropping.
 *
 *
 * ==========================================================================
 *  Group Enemy Drop Percentages
 * ==========================================================================
 *
 * Available Enemy Notetags:
 *
 * <Group Item x1 - x2: y%>
 * <Group Weapon x1 - x2: y%>
 * <Group Armor x1 - x2: y%>
 *
 * This sets a group of Items, Weapons, or Armors to have a y% chance of 
 * dropping.
 *
 *
 * For example:
 *
 * <Group Item 3 - 20: 50%>
 *
 * There is a 50% chance of 1 Item in this group of dropping.
 *
 *
 * ==========================================================================
 *  Creating Item/Armor/Weapon Groups
 * ==========================================================================
 *
 * Another feature added in this Plugin is the ability to set Items into
 * specific groups and base drops off of these groups.
 *
 * Use the following Item/Weapon/Armor notetag:
 *
 *  <Drop Group: group-name>
 *
 * to set an Item/Weapon/Armor to a specific group.
 *
 *
 * For example: <Drop Group: Bug>
 *              <Drop Group: Fire>
 *              <Drop Group: Giant Ants>
 *
 * One Item/Weapon/Armor can be a part of multiple groups.
 *
 *
 * ==========================================================================
 *  Giving Item/Armor/Weapon Groups
 * ==========================================================================
 *
 * In order to have an Enemy drop Items based off of a group, use the 
 * notetag:
 *
 * <Drop Group my-group: y%>
 *
 * This will set it so there is a y% chance of one item within my-group
 * to be dropped when the Enemy is defeated.
 *
 *
 * For example: <Drop Group Fire: 50%>
 *
 * This would make it so there's a 50% chance that one Item/Weapon/Armor
 * from the "Fire" group will drop when the Eney is defeated.
 *
