Class LegacyEnumQueryStrategy

Legacy Javadocs don't have classes for each enum constant, instead they're in the format:

<h3>Enum Constant Detail</h3>
<a name="<prototype>"></a>
<ul class="blockList">
  // actual table data
</ul>
  // ... and so on
Copy

Here we try to work around this issue by manipulating the HTML, adding a div that wraps each pair, and then selecting those divs.
