 ==============================================================================
 Overview
 ==============================================================================

 This script provides the ability to run RGSS3 methods/formulas during the
 start and end of turns.
 
 These can be used for: 
 
 actors/classes/weapons/armors/states/enemies
 
 Global - always affects turn start and end
 Actors - affects all turn start and end when the actor is present in battle
 Classes - affects all turn start and end when the class is present in battle
 Weapons/Armors - affects all turn start and end when the weapon/armor
                  is equipped by any actor in battle
 Enemies - affects all turn start and end when the enemy is present in battle
 States - affects all turn start and end when the state is present in battle
 
 ==============================================================================
 Set-Up
 ==============================================================================
 
 Just put this script into a blank slot above main but below materials
 (see compatibility section) and start tagging and making your own formulas
 
 ==============================================================================
 Method flow
 ==============================================================================

 This is the normal flow of the custom methods based on the default set-up
 
 Global
 Actor
 Class
 Equips
 Actor States
 Enemies
 Enemy States
 
 ==============================================================================
 Tags
 ==============================================================================
 
 -------------------------------------------------------------------
 For turn_start
 -------------------------------------------------------------------
 <start_turn_start_ext>
   formula
 <end_turn_start_ext>
 
 -------------------------------------------------------------------
 For turn end
 -------------------------------------------------------------------
 <start_turn_end_ext>
   formula
 <end_turn_end_ext>

 Use battler to denote the battler, equip to denote the equipment,
 state to denote the state
