HighlightingSystem插件使用（边缘发光），导入Unity里面可能会报错，不过没关系，直接注释掉就可以了，我用的是Unity5.1的版本

可以看到如下文件夹，HighlighingSystemDemo是一些实例，可以看一下，然后Plugins里面就是插件的相关代码 了(HighlightingSystem plug in (edge light-emitting), import Unity may be wrong, but it does not matter, simply note off, you can use, I use the Unity5.1 version
You can see the following folder, HighlighingSystemDemo is some examples, you can see, and then Plugins is the plug-in related code)
