The method copy takes no argument and returns a deep copy of the XML
object it is called on where the internal parent property is set to null.
Here are some examples using the method:
  var god = <god>Kibo</god>;
  var godCopy = god.copy();
  alert(godCopy === god); // show false
  alert(godCopy == god); // shows true
  var gods = <gods>
    <god>
      <name>Kibo</name>
    </god>
    <god>
      <name>Xibo</name>
    </god>
  </gods>;
  var godCopy = gods.god[0].copy();
  alert(godCopy);
  /* shows
  '<god>
     <name>Kibo</name>
   </god>'
  */
  alert(gods.god[0].parent() === null); // shows 'false'
  alert(godCopy.parent() === null); // shows 'true'
