/**
 * jQuery Ajax Rater Plugin
 *
 * This rater is based on the code Ritesh Agrawal did. Unfortunatly his CSS and the hover technique breaks in some browsers.
 * So i thought, why not use the best CSS star-rater known to man kind and throw it in the mix.
 * I have used the CSS and technique from Komodo Media since it is stable and tested on many, many browsers.
 *
 * This rater compared, has no cancel button. But i think we can live with that :)
 * To avoid conflicts i have changed the function name.
