【问题描述】：
如何在使用 Angular 的 ng-view 指令时使用 Addy Osmani 的 uncss。
假设我有两个视图，我想使用 uncss。使用 uncss 测试这些视图上是否有任何未使用的样式并创建一个新的样式表。
文件结构 - 应用
-styles
----- parts
-----_bootstrap.scss
-----_navigation.scss
----- main.scss
-views
----- home.html
----- about.html
-index.html
不幸的是，我无法使 uncss 与 ng-view 指令一起使用，因为我相信它是异步的，并且尚未创建 html。
html index.html
<!-- /build -->
</head>
<body ng-app="navigationApp">
<!-- Add your site or application content here -->
<div class="container" ng-view=""></div>
</body>
html home.html
<div class="first"><h1>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Libero, ullam, impedit iste eaque deserunt quae dolorum atque labore nihil ut sunt repellendus inventore nulla. Expedita mollitia fugiat eveniet quasi ipsa.</h1></div>
<div class="second"><h2>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Quaerat, pariatur, ex quod necessitatibus optio provident hic quasi dolorem molestiae similique velit accusamus id suscipit nesciunt ab repudiandae beatae praesentium dolores.</h2></div>
<div class="last"><p>asdl;fkjasdflkjas dflkajsdf;lkajsdf;lkj Lorem ipsum dolor sit amet, consectetur adipisicing elit. Doloribus, recusandae necessitatibus reprehenderit libero porro. Suscipit, soluta, reiciendis commodi vero consequatur officia veritatis pariatur iusto deleniti amet minima ducimus nostrum facilis.</p><div>
这个例子毫无意义，我只是想知道是否有可能使 uncss 与 angular ng-view 或 ui-router 一起工作。如果是这样，我该如何正确编写 gruntfile？如果没有，有什么解决办法吗？因为这是一个非常棒的插件。
我已将它包含在我的 gruntfile.js 中
