title: Nanoscroll doesn't support multiple contents
body: <p>I'm using Tabulous.js script with NanoScroll.js
  Here is my code :</p>
  
  <pre><code>&lt;div id="tabs_container" class="nano"&gt;
    &lt;div id="tabs-1" class="overthrow content"&gt;
     short text
    &lt;/div&gt;
    &lt;div id="tabs-2" class="overthrow content"&gt;
      very long text
    &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>and</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
       $(function () {
          $(".nano").nanoScroller({scroll: 'top'});
       }
  &lt;/script&gt;
  </code></pre>
  
  <p>As the first content is short, nano is not used, but for the second content, it should appears.</p>
  
  <p>Content is a class, that's why I though we could use multiple contents. Am I wrong ?</p>
  
  <p>Any advises on this ?</p>
  
  <p>Thanks in advance</p>
