Detailed Description

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

A generic matcher algorithm which outputs all combinations of elements with the number of shared hits as a weight.

It does only use those collection items, which do not have a taken flag.
