 ** Description
 
 This script allows you to have an equip pull parameters from a different
 equip depending on which actor is using it.
 
 For example, a long sword might give 20 ATK to one actor, but give 60 ATK
 to a different actor, based on the actor ID or the actor's class ID.
 
--------------------------------------------------------------------------------
 ** Installation
 
 In the script editor, place this script below Materials and above Main

--------------------------------------------------------------------------------
 ** Usage
 
 For each weapon and armor, use the note-tag
 
 <actor equip: ACTOR_ID, EQUIP_ID>
 
 Where the ACTOR_ID is the ID of the actor that is using the weapon or
 wearing the armor, and the EQUIP_ID is the ID of the weapon or armor that it
 should read parameters from. 
 
 Class-based equip parameters are also available, using the note-tag
 
 <class equip: CLASS_ID, EQUIP_ID>
 
 Note that if both actor and class ID's exist for an equip, then the actor's
 ID will be used since it is more specific and therefore has higher precedence.
