Added callback boolean to the options hash that gets passed into CollectionTableView to control which column headings trigger events on the parent view.  Also moved some html rendering into the gradebook.tt template.  There is an issue on hard reset.  click a set_id or user_id then hard reset the page.  The page now displays the gradebook table but with the title of either the set_id or user_id last displayed.  I'm not sure how to fix this right now.  Any suggestions?
