Detailed Description

Used to compare pointers of TriggerElements.

To establish equality of trigger elements, we check (a) that their id's match and (b) that they come from the same RoI. To check that the RoI is the same, we check check the RoI features, as these will never be slimmed (unless the whole branch is removed).
