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

 This script provides the ability to run RGSS3 methods/formulas during the
 equip and unequip of weapons/armors
 
 These can be used for: 
 
 actors/classes/weapons/armors
 
 Actors - affects all equip/unequip by the actor
 Classes - affects all equip/unequip by the actor that uses that class
 Weapons/Armors - affects all actors that equips/unequips the item
 
 ==============================================================================
 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
 
 Item Unequip
 Actor Unequip
 Class Unequip
 Item Equip
 Actor Equip
 Class Equip
 
 ==============================================================================
 Tags
 ==============================================================================
 
 -------------------------------------------------------------------
 For equip

 <start_equip_ext>
   formula
 <end_equip_ext>
 
 -------------------------------------------------------------------
 For unequip

   formula

 Use self to denote the actor that equips/unequips
