title: Jazzy is not working as expected for generating swift documentation
body: <p>After doing some research on the best way to document swift code. I came across Jazzy and how simple it was to implement. So I follow the installation section of the <a href="https://github.com/Realm/jazzy" rel="noreferrer">Jazzy Documentation</a>. I run </p>
  
  <pre><code>sudo gem install jazzy
  </code></pre>
  
  <p>Then I navigate to the root of my project, in the terminal, and run <code>jazzy</code> which creates a folder called "docs" with a website that displays documentation for 1 class. I have 87 classes which I can visibly see jazzy looping through in the terminal output.</p>
  
  <p>I've read the <a href="http://nshipster.com/swift-documentation/" rel="noreferrer">NSHipster Tutorial</a> about documenting code which also links you to the <a href="https://github.com/Realm/jazzy" rel="noreferrer">Jazzy Documentation</a> as well as the <a href="https://developer.apple.com/library/prerelease/ios/documentation/Xcode/Reference/xcode_markup_formatting_ref/index.html#//apple_ref/doc/uid/TP40016497-CH2-SW1" rel="noreferrer">Markup Formatting Reference</a>. I've documented some code, which Xcode displays correctly in the side pane or right clicking the function or class. So i'm fairly certain that my syntax is correct.</p>
  
  <p>I took some time to compare that 1 file to the another file that isn't being displayed and I don't see anything out of the ordinary with regards to format.</p>
  
  <p>I'm running:</p>
  
  <ul>
  <li>jazzy version: 0.3.2</li>
  <li>Xcode version: 7.1</li>
  <li>Swift version: 2.1</li>
  <li>OS X El Capitan Version: 10.11</li>
  </ul>
  
  <p>My overall question is; Why isn't jazzy producing documentation for all classes and how can I fix this issue?</p>
