title: How to clear all selected items in a SELECT input using jQuery?
body: <p>I am think this should be fairly easy, but struggling a bit ... I have a <code>SELECT</code> input element that allows the user to select multiple items. I would like to provide a mechanism for them to clear all selected items, probably will just be a <code>SPAN</code> tag or something similar. </p>
  
  <p>Anyway ... using jQuery, how I would I clear the selection on the <code>SELECT</code> input element so no items are selected.</p>
