 /*:
 * @plugindesc Allows you to create custom stats for damage formulas or any other use.
 * @author Bobstah
 *
 * ============================================================================
 * Introduction
 * ============================================================================
 * A simple custom stat plugin. Does not display the stats in
 * the actor Status window.
 *
 * ============================================================================
 * Notetags
 * ============================================================================
 * Actor/Enemy/Class
 * <CustomStat: statName=statValue>
 * statName - The name you want to reference this stat with.
 * statValue - The default value of your stat. Must be a number.
 *
 * Weapon/Armor/State
 * <CustomStat: statName+statValue>
 * <CustomStat: statName-statValue>
 * ============================================================================
 * Examples
 * ============================================================================
 * After setting a custom stat to an actor/enemy, you reference
 * it in damage formulas or other code just like any other
 * stat. Below is a sample damage formula for the a stat
 * named 'sanity':
 * 100 + a.sanity
 *
 * Let's say you gave the enemy a stat named 'insanity':
 * (100+ a.sanity) - b.insanity
 *
