/**
 AJAX RATING SCRIPT
======================

The rating function is called using ajaxRate(ID,rating) where ID is the ID of current template
to be rated and rating is a standard rating from 0 to 5. 

An image could then be linked this way:

<a href="javascript: ajaxRate(007, 2)<img src="2-star.png" /></a>

The script has to be included in either the head or body part of the HTML file.

<script language="JavaScript" src="ajaxrate.js"></script>
