title: Find tags with no classes and add a class
body: <p>I need jQuery to add a class to any form element that has no class allready. I made up a function, the hasNoClass.</p>
  
  <p>Is it possible to do in the real life?
  Pseudo code: add class to "classless" form tag
  jQuery("form").hasNoClass().addClass("gotClass");</p>
  
  <p>Alternatively it can be done by a "add class to 3rd form start tag on page. No clue how that would be either, but there may be a position or count function
  Pseudo code: add class to third form tag:
  jQuery("form").postition("3").addClass("gotClass");</p>
  
  <p>Wow! That was two questions! I only need the one but answer on both would be appreciated just for the sake of knowing and maybe future use.</p>
