#==============================================================================
# CHANGELOG
# - ver0.63  2013.01.05   aliasing make_damage_value, compacting script
# - ver0.62  2012.12.29   give up on aliasing make_damage_value,
#                         rewrite method make_damage_value,
#                         add class weapon efficiency, add debug mode,
#                         add limiter, add damage from item option
# - ver0.61a 2012.08.26   Trying to fix make_damage method on Game_ActionResult
# - ver0.61  2012.08.16   Trying to alias make_damage_value method
# - ver0.60               Initialization

# INTRODUCTION
#   This simple snippet is intended to amplify your damage based on your current
#   weapon.
#   You have char A (which class is Archer class) and B (Berserker)
#   A can wield Sword and Bow, B only can wield Sword
#   You think there's no way an archer could defeat berserker on swordmanship
#   Then this script can help you set A's weapon efficiency on sword to 0.5 while
#   B's weapon efficiency on 2.0
#
#
#   This WE system can be applied to Actor and/or Class. And you can also set
#   the WE calculation for Actor and Class to Sum, Max, Avg, or Mult
#
#   Here is another example on Avg method:
#   B has personal 2.0 WE (weapon efficiency) on sword
#   B1 has no personal WE set on sword
#   C has personal 1.3 WE on Sword
#   Berserker class have 1.5 WE on sword
#   Cleric class has no WE set on sword
#
#   Final WE on B will be ( 2.0 + 1.5 ) / 2 = 1.75
#   Final WE for B1 will be 1.5 (only using class WE)
#   Final WE for C will be 1.3 (only using actor WE)
#
#==============================================================================
# INSTRUCTION
#  - Simply write <weapon_efficiency: weapon_id, value> on class and/or actor's
#    note
