Add track filtering to Schedule pages

While customizing COD for one of our clients at Mediacurrent, we had a request to highlight sessions based on track in the schedule view. This particular use case had tracks that were not always in the same room and needed the ability for users to quickly visualize the tracks of interest by clicking on the track name, which would result in the appropriate cells being highlighted. COD currently uses a CCK text field for tracks on the Session content type which I modified with the PHP option to pull in from a vocabulary associated with the Event (via an added nodereference field). I'm including a small jQuery file that accomplishes the highlighting but it will need to be modified for out-of-the-box COD users. It assumes that the session tracks are printed on the schedule page (either via Views, theming, or Panels) and are printed as links. They are not required to be taxonomy terms as we modified them. In our case, the use of taxonomy allows graceful degradation by taking users to the taxonomy page which lists the sessions if javascript is not available or impractical. It would also be useful if organizers were displaying BOF's that had the same terms as they would also be highlighted. If there is any interest, I can post additional code changes we used to accomplish this.

This javascript simply reverses the regex used in cod_session.module to generate track classes to search and add a highlight class to the selected track when clicked. drupal_add_js() needs to be called in either cod_session.module or in the theme as well.
