/*************************************************
 This is hacked version of star rating created by <a href="http://php.scripts.psu.edu/rja171/widgets/rating.php">Ritesh Agrawal</a>
 It thansform a set of radio type input elements to star rating type and remain the radio element name and value,
 so could be integrated with your form. It acts as a normal radio button.
