一：前言
对于面板赋值或Find绑定UI组件，我们可以使用一种工具化的方式去自动生成代码并绑定对象，增加效率
分为logic和view，view层是UI界面上的组件，每次都会自动生成并覆盖，logic层是逻辑
二：使用
例如一个UI界面，我们只需要做成预制体并在Project下右键预制体，选择AutoGen/Create View则会自动生成view和logic两个脚本，logic是我们要编写逻辑的脚本，view是每次都会自动生成并覆盖的脚本
三：说明
——以下几个路径都是可以自定义的（view和logic生成的路径、view和logic模版文件的路径）
——可以自定义忽略的组件类型列表
——只会生成对象名带下划线的
四：代码实现
