7 * @source This plugin is heavily influenced by MochiKit's serializeJSON, which is
8 *         copyrighted 2005 by Bob Ippolito.
9 * @source Brantley Harris wrote this plugin. It is based somewhat on the JSON.org
10 *         website's http://www.json.org/json2.js, which proclaims:
11 *         "NO WARRANTY EXPRESSED OR IMPLIED. USE AT YOUR OWN RISK.", a sentiment that
12 *         I uphold.
