# Skill Shop
# Author: Game_guy
# Date: June 7th, 2009
# Version: 2.2
#===============================================================================
#
# Intro:
# What this script does is act as a shop but sells skills instead.
#
# Instructions:
# 1: First how do you want it setup? Theres two ways
#    1: -Any person can learn any skill
#    or
#    2: -Classes learn different skills then other classes
#
#    Go down to UseClasses and set it to false for 1: or true for 2:
#
# 2: Ok now that thats over lets move onto price. Go down to CONFIG PRICE and
#    follow the instructions there.
# 
# 3: Skip this step if you set UseClasses to false.
#    Go to CONFIG CLASS SKILLS and follow the instructions there.
#   
# 4: Ok so everythings setup now. Time to actually find out how to open the
#    skillshop right? You use this line
#    $scene = SkillShop.new([skill id's go here])
#    example
#    $scene = SkillShop.new([1, 2]) will make a shop with the skills
#    Heal and Great Heal
#
# 5: Ok the script now is able to make it where only skills are learnable at
#    certain levels. Go to CONFIG LEVEL and follow instructions there.
#
# 6: Ok so now there's a new option that sorts the skills in the following.
#    Alphabetical
#    Reverse Alphabetical
#    Numeric (Sorts it by Id)
#    Reverse Numberic
#    Price
#    Reverse price
#    At default its at numeric but to change it use this,
#    $game_system.ssort = 0,1,2, or 3.
#    0 = Numeric, 1 = Reverse Numeric, 2 = Alphabetical,
#    3 = Reverse Alphabetical, 4 = Price, 5 = Reverse Price.
