title: Render List of Lists with StringTemplate
body: <p>Please help me to render the following Java structure with StringTemplate:</p>
  
  <pre><code>List&lt;List&lt;String&gt;&gt; listOfListsOfStrings;
  </code></pre>
  
  <p>The output should be as follows (where ListXStringY is a string contained in position X, Y):</p>
  
  <ul>
  <li>List1String1, List1String2, ...</li>
  <li>List2String1, List2String2, List2String3, ...</li>
  <li>...</li>
  <li>ListNString1, ...</li>
  </ul>
  
  <p>The number of strings in different second-level lists can vary. Thank you!</p>
