Component メニューに項目を追加します
        The script will be placed in the component menu according to menuName. For example, if the menuName is "Rendering/DoSomething" the new menu will be called DoSomething and appear as a child of the Rendering group in the Components menu.
If menuName is "" or starts with "/" the component will be hidden from the menu. 
Lower order values place the new item higher to the top of the Component menu.
