title: See if div contains another div with a particular class?
body: <p>Say I have:</p>
  
  <pre><code>&lt;div class="outer"&gt;
  
  &lt;div class="foo bar"&gt;&lt;/div&gt;
  
  &lt;/div&gt;
  </code></pre>
  
  <p>How can I check to see if <code>$('.outer')</code> has a div with a class named "bar" within it?</p>
