 Custom Equip Conditions v1.01
 by AdiktuzMiko
 --- Date Created: 08/29/2014

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

 This script provides the ability to use RGSS3 methods/formulas as custom
 requirements for equipping an item. Use it with the default RGSS3 scripts
 or couple it with custom scripts (like custom stat systems) for more
 custom requirement possibilities.
 
 The actor must be able to equip the item under normal conditions (equip types) 
 before the custom requirement is even checked.
 
 ==============================================================================
 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
 
 ==============================================================================
 Tags
 ==============================================================================

 <start_custom_req>
   formula
 <end_custom_req>
 
 Use the variable "actor" to denote the actor being checked
 
 Example: The item is only equippable if the actor's level is greater
 than 5
 
 <start_custom_req>
   actor.level > 5
 <end_custom_req>

 ==============================================================================
 Compatibility
 ==============================================================================

 This script aliases Game_Battler's equippable? method
