* Technorati Click Tracking v1 // 2008.10.31
* @author    Duane Barlow
*   To any item you want to track clicks on, add: onclick="$(this).track('click-path');" to the element
*   to any parent nodes you want to appear in the click path hierarch, add the same thing to its onclick
*       - only anchor tags will fire a pixel, the others will be used to assemble the click path
*       - if you want the click path to terminate anywhere, begin the clickpath with a '/' and that will be the first to come after the '/clicks/' node
