title: importHTML with class declaration
body: <p>The code <code>=ImportHtml(“http://en.wikipedia.org/wiki/Demographics_of_India“; “table”;4)</code> is working for me.</p>
  
  <p>I want now to specify HTML element with a certain CSS class. For importXML it works like <code>=importxml(http://example.com,"//*[@class='teaser']")</code>  - how should it work for importHTML?</p>
