title: Deselect/Select all checkboxes in Class for D3
body: <pre><code>function deselectAll(){
  d3.selectAll('input').property('checked', false);
  drawUpdate();
  }
  </code></pre>
  
  <p>I'm trying to deselect all checkboxes listed under a certain class because I have two seperate classes for two sets of checkboxes. Is it possible to do that with D3? I tried replacing 'input' with '.checkboxClass'.</p>
