// @description Adds checkboxes next to HIT links so that you can set a checkpoint.
// A checkpoint will notify you that you've already seen a HIT by
// changing the HIT link to display the date the checkpoint was set. A
// well-placed checkpoint is useful when browsing HITs by creation date
// (newest first) because it will alert you that you've already seen the
// checkpoint HIT and probably all the HITs that come after it.
// It's best to place a checkpoint on a HIT that won't be recreated
// because recreated HITs jump to the first page.
// mmmturkeybacon Color Coded Search with Checkpoints has the same
// functionality built-in. So if you have that installed you don't
// need this script.
