插件介绍
Augury是Google Chrome开发工具的扩展，用于在运行时调试和可视化角度应用程序。
augury是一款可以安装在谷歌浏览器上使用的Angular2专用的chrome调试插件，现在和VUE对比起来，确实可以看出有谷歌支持下angular2会更活跃，我个人认为2年后恐怕VUE无法与之抗衡，Augury还处于beta阶段，也还有很多问题，但是有些地方已经非常方便开发和调试了，大家可以来尝尝鲜！
官方介绍：
Extends the Developer Tools, adding tools for debugging and profiling Angular 2.0 applications.
Augury is a Google Chrome Dev Tool extension for debugging Angular 2 applications. Treat this as a "developer preview".
Augury特性：
1 用augury查看component结构；
ng2-admin项目结构
ng2-admin对应的的component结构
运行应用，打开浏览器查看页面，在开发者工具中可以看到，ComponentTree，这里可以非常清晰的看出appComponent的结构图，hover到component上面时，页面也会显示相应的位置。
2 查看单个Component的具体属性和方法；
3 可视化显示component关系；
4 查看router结构
结构真是一目了然，真是太牛逼了。
这些router结构，component结构可以帮助看看应用的结构是否存在问题。components中的具体方法，属性，用来调试具体内容的逻辑,有时候想换设一个值调下看看，可以直接在properties中改掉。

-- New in version 1.2.4
* Add new support for decorators: @ViewChild, @ViewChildren, @ContentChild, and @ContentChildren. Now we display these decorators, along with the type selector information, in the UI.
* Add proper type information to State panel view. Instead of displaying "Object", for example, we display the real type of that object, for example "NgModuleLoader". We do this by retaining the type information across serialization. (Objects are serialized in the backend and then transmitted to the frontend, and the type information was being lost during this process. Now it is retained.)
* Refactor the decorator metadata system so that it works for nested objects. In 1.2.3, if you have a @ViewChild(Foo) reference on your component, and you expand that object in the State view, any @Input() or @Output() decorators on the "Foo" object are now displayed in the UI. (Previously decorator metadata was only generated for toplevel components.)
