## Author:   Stephen Blum
## Date:     April 28, 2008
## Filename: adtracker.js
## ------------------------
## Purpose:  Convert all element classes known as "TrackedAd" into
##           trackable links. The companion tracking code can be found in
##           "Main" in the function system_link_track().
