title: Make classes appear on TOC in Sphinx
body: <p>I'm starting to document a few python classes using ext.autodoc. I have several *.rst files with content such as</p>
  
  <pre><code>========
  mymodule
  ========
  
  .. automodule:: mymodule
     .. autoclass:: myclassA
         :members:
     .. autoclass:: myclassB
         :members:
  </code></pre>
  
  <p>plus an index.rst:</p>
  
  <pre><code>.. toctree::
     :maxdepth: 2
     mymodule
  </code></pre>
  
  <p>'mymodule' shown in the table of contents, but I'd also like to see the classes in the TOC too:</p>
  
  <ul>
  <li>mymodule
  <ul>
  <li>myclassA</li>
  <li>myclassB</li>
  </ul></li>
  </ul>
  
  <p>How can I make sphinx create something like a section for each class? Or is there a good reason not to do so?</p>
  
  <p>thanks</p>
