// postLoadUrchin.js version 0.1
// copyright 2007 Michael VanDeMar
//
// Allows for including the Urchin Javascript 
// file at the end of an html page, instead
// of at the beginning
//
// upload this file to your server, 
// and include it in your webpage as such:
//
// <script src="/path-to-include/postLoadUrchin.js" type="text/javascript">
// </script>
//
// Far each link that you wish to attach tracking to, 
// include pl_{functionName}="param" in it,
// so:
// <a href="http://www.example.com" onclick="javascript:urchinTracker('/outgoing/example_com');">Anchor text</a>
//
// would become:
// <a href="http://www.example.com" pl_urchinTracker="/outgoing/example_com">Anchor text</a>
//
// Before your closing body tag,
// include the normal Urchin code.
