/*:
* @plugindesc This plugin allows a user to modify stats on Classes or Enemies based on other stats.
* For example, raising maximum HP by a percentage of their defense.
* @author Zevia
*
* @help In a class or enemy's note box, put <link firstStat: x secondStat>,
* where firstStat is the stat you want to increase, secondStat is the stat you
* want to reference to increase the first stat by, and x is the percentage you
* want to increase based on the secondStat.
*
* As an example, <link mhp: 50 def> would translate to "increase this class's
* maximum hp by 50% of the class's defense".
*
* You can tie multiple stats to one stat by separating them with commas.
* For example, <link mhp: 50 def, 40 luk> would mean, "increase this
* class's maximum hp by 50% of the class's defense and 40% of the class's
* luck".
*
* If you want to be able to define a class or enemy's entire stat in relation
* to another stat, you can change the minimums of their stats. As an example,
* if you want a class's maximum HP to be solely dependent on their DEF and
* LUK, you can change the minimum HP parameter to 0, then do <link mhp: x def, y luk>
*
* @param mhp
* @text HP minimum
* @type number
* @desc The minimum value for HP. By default, it's 1.
* @default 1
*
* @param mmp
* @text MP minimum
* @type number
* @desc The minimum value for MP. By default, it's 0.
* @default 0
*
* @param atk
* @text ATK minimum
* @type number
* @desc The minimum value for ATK. By default, it's 1.
* @default 1
*
* @param def
* @text DEF minimum
* @type number
* @desc The minimum value for DEF. By default, it's 1.
* @default 1
*
* @param mat
* @text MAT minimum
* @type number
* @desc The minimum value for MAT. By default, it's 1.
* @default 1
*
* @param mdf
* @text MDF minimum
* @type number
* @desc The minimum value for MDF. By default, it's 1.
* @default 1
*
* @param agi
* @text AGI minimum
* @type number
* @desc The minimum value for AGI. By default, it's 1.
* @default 1
*
* @param luk
* @text LUK minimum
* @type number
* @desc The minimum value for LUK. By default, it's 1.
* @default 1
