//              completed HITs that are still pending approval.
//              Displays the total automatic approval time when
//              the mouse pointer hovers over the status field.

/*
 * Automatic approval data is saved whenever a HIT page is unloaded. Usually when a 
 * HIT page is unloaded it means the HIT was submitted, but this isn't necessarily
 * so. It could also be that the user accepted the HIT, then closed the tab to
 * work on the HIT from his queue later. If this is the case, once the user eventually
 * submits the HIT the automatic approval data will be updated when the page unloads.
 * However, if the user returns the HIT then automatic approval data will have been
 * saved in local storage that isn't associated with any completed HITs. There's really
 * no good way to prevent this from happening or to remove the data.
