title: Create a cookie if (and only if) it doesn't already exist
body: <p><strong>I want to:</strong></p>
  
  <ol>
  <li>Check to see if a cookie with name of "query" exists</li>
  <li>If yes, then do nothing</li>
  <li>If no, create a cookie "query" with a value of 1</li>
  </ol>
  
  <p>Note: I am using jQuery 1.4.2 and the <a href="https://github.com/carhartl/jquery-cookie" rel="noreferrer">jQuery cookie plugin</a>.</p>
  
  <p>Does anyone have any suggestions as to how I can do this?</p>
