title: Can't find @EnableSwagger annotation
body: <p>I just wanted to documente my spring rest application. Following the how to with springfox I added as a dependency in my pom.xml:</p>
  
  <pre><code>&lt;dependency&gt;
      &lt;groupId&gt;io.springfox&lt;/groupId&gt;
      &lt;artifactId&gt;springfox-swagger2&lt;/artifactId&gt;
      &lt;version&gt;2.7.0&lt;/version&gt;
  &lt;/dependency&gt;
  </code></pre>
  
  <p>the jar is downloaded correctly but I can't find @EnableSwagger2 annotation nowhere.</p>
