*  Class  : CbmRichMatchRings
*  Description: Task class for matching a reconstructed CbmRichRings with a simulated
*               CbmMCTrack. The matching criterion is a maximal number of common
*               hits/points. The task fills the data class CbmRichRingMatch for
*               each CbmRichRing.
