// This script creates multiple prefab by Multiple Prefab Creator  .
// Use it to create Prefab or prefabs  from the selected GameObject(s).
// It will be placed in you want which folder.... you have to write it's name to "Folder name" at Multiple Prefab Creator Window
// if you didn't write name of folder , Multiple Prefab Creator creates your prefabs in Main Assets Folder.
// if you did write an uncreated folder name , Multiple Prefab Creator won't create prefabs
// if you want create prefabs at "child folder of a folder" , you have to write this  "/"  between two folder
// example Editor/Prefab/Buildings
//**
//if you selected gameobjects and you  want to shortcut for create to prefabs
// you can use Ctrl+Shift+Alt+P .... This shortcut  direct create prefabs
// you can open Multiple Prefab Creator window , you have to click Multiple Prefab after click Multiple Prefab Creator Window at Menu
// if you can want to  shortcut for open Multiple Prefab Creator window  , you can use Ctrl+Shift+Alt+O...
