Detailed Description

Form complete list of DTrackCandidate objects using the lists formed from the CDC and FDCCathodes candidate factories (DTrackCandidate_factory_CDC and DTrackCandidate_factory_FDCCathodes).

Track finding starts by looking for candidates independently in the CDC and FDC. The results of those first passes are used as input here where a single list is made containijng all candidates.

This will attempt to identify any candidates that should be merged into a single candidate, mainly if a both a CDC and FDC candidate were found for the same track.

In addition, stray CDC hits that did not belong to any candidate are merged into existing candidates if possible.
