Unity3D创建C#自定义模板快速实现基类接口

根据模板类，我们可以快速的创建一些我们想要的脚本内容，比如我们有接口要在子类上实现，就可以写一个对应的模板，每次创建脚本就会帮我自动实现接口，特别是在UI脚本上经常需要用到这个需求。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class #SCRIPTNAME# : MonoBehaviour {

	void Start () {

	}
	
	void Update () {

	}
}

我们可以根据项目需求自行拓展模板。
