How to Use:

You will add "$skill_shop =[Id of Skill]" 
To Call Script to set id of skill for sell.
You will add "$scene = Scene_Skill_Shop.new" 
To Call Skill Shop Windows.

Example:
$skill_shop = [1,2,3,6,7]
$scene = Scene_Skill_Shop.new

You can turn on/off option under "# Setting".
You can set text to use in Skill Shop under "# Learn Text".
You can add "[p-Price-]" for set Skill Price at Note in Skill Database.
Example : For set Price to 150

[p150]

You can set Skill that the fighter each person can learn under "# Hero Data".

You will setting look like this in Hero Data
[ID of skill, Level requirement for learn]

Example : if you want actor id 1 can learn skill id 1 at Lv 4
and can learn skill id 2 at lv 3. You will setting look like this

1 => [ #Id of Actor
 
  [1,4],[2,3],
 
  ],
