/**
 * New phone switching code
 *
 * Replace phone numbers easily on a website.
 *
 * How to use this script:
 * - Copy this script (phone.js) to the root directory of the site
 * - Add the following 2 lines to the footer of the site, right before </body>
 * <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
 * <script type="text/javascript" src="phone.js"></script>
 * - Edit the bottom of this file with the proper numbers, images, referrers, etc.
 *
 * Future changes
 * - Support for multiple numbers (ex. Call (800) 123-1234 or 504-555-5555)

 * Changelog
 * - 2010-06-15: Changed the _getReferalValue() to use a regular expression
 *               instead of nested loops and conditionals.
