* ■ System Information:
* ============================================================================
* 
* A short description of how this system works;
* 
* As you take damage from hp, willpower goes down, and other stats (atk, def,
* mat, mdf, agi and luk) each go down in accodance with the will multiplier.
* When you are at full hp mp and tp, the other stats will be normal. 
* 
* 
* A more detailed explanation; 
* 
* This plugin creates two new stats - will, and willrt. 
* 
* Will Rate (willrt), is a stat that is solely based on combined hp, mp, and 
* tp rates. Eg, when all are full, will rate will also be full (1.0 / 100%).
* This value can NOT be controlled by the player - other than whatever control
* they have over hp, mp and tp via potions and skill etc.
* 
* Will (will), is a simple stat that is meant to be used within the will power 
* multiplier function to allow for the multiplier value to be different when
* certain actors/classes/enemeies/equips or states are in effect. 
* By default, this value is 0.
* 
* The willpower multiplier function is used to determine parameter LOSS.
* Notetags can be used to allow each actor / enemy to use a different 
* multiplier function from one another.
* 
* If all of this sounds extremely confusing to you, know this; 
* Your stats go down as your hp/mp and tp does. The higher your 'will' stat, 
* the less the parameters go down when not at full will rate. 
* And you can also customize the formula that determines the param loss. 
* 
* Additionally, as all battlers now have shiny new stats called 'will' and 
* 'willrt', you can use these in skill formulae as shown below;
* (a.will * 10) * (1.0-b.willrt)
* Note - I have not tested this formula, it is only an example.
* 
* 
* ============================================================================
* ■ Notetags:
* ============================================================================
* 
* <will: VALUE>
* VALUE should be the value you wish for the actor, class, enemy, equip or 
* state to give to the battler for the will stat.
* VALUE should also be a small value (0.05 would increase damage 5% when crit)
* 
* <will funk: this.level/100+1.0>
* This notetag changes the default formula used to determine an actor or
* enemies base critical damage rate (before quires and states etc).
