title: Angular Material: date picker, missing theme?
body: <p>I got some trouble integrating the <a href="https://material.angularjs.org/latest/demo/datepicker" rel="nofollow noreferrer">Angular Material date picker</a> in my application:</p>

  <p>Looking at the diff between my local version and the demo version, I noticed that I don't have any <code>&lt;style md-theme-style&gt;</code> element in my head. What am I missing? :)</p>
  
  <p>I added the <code>ngMaterial</code> dependency to my app, and included the <code>./node_modules/angular-material/angular-material.scss</code> file through Webpack. Moreover, I didn't override the <code>$mdThemingProvider</code> configuration.</p>
  
  <p>Any clue? :)</p>
