Detailed Description

template<class ACollectorItem, class ACollectionItem>
class Belle2::TrackFindingCDC::AdderInterface< ACollectorItem, ACollectionItem >

Base class for a findlet, which uses a reduced/thinned list of weighted relations between collector and collection items to absorb the matched collection items into a collector item.

Please do not implement any logic which collection items should be added to which collector item, but handle all this in a selector (see below).

Most likely, the full stack is used as follows:

match two lists of elements (Collectors and Collections) resulting in a list of weighted relations among those
select only some relations using a certain criteria (this is where the difference between Collector and Collections comes into place)
add the found relations by absorbing the collection items into the collector items.

Please note that the CollectionItems are therefore const whereas the CollectorItems are not. All the passed WeightedRelations lists must be sorted.

Most of the provided selectors are built to match many collection items to one collector item.
