Unity热更新Lua 插件Emmylua 补上CS代码属性方法呼出小工具
使用Emmylua的时候尽管可以给本身Lua文件编辑属性函数注解，但是缺少Unity端CS代码的属性方法呼出, 平时也需要经常使用到。写了个小工具，按照Emmylua的规格导出一份CS代码类属性方法等的注解文件，以方便使用CS代码。编译CS代码为Lua注解, 自己写的代码也一并导出

小工具还有很多不足，比如泛型问题。
编译导出的文件只是注解文件，不需要和其他热更新文件一起打包。
如有需要可以在工具中修改导出位置, 添加一些想排除的类型等 (请随意)。
EmmyLuaUnity插件 好像也有这个功能。求推荐更好的插件。
