//
//  HMdcTrkCand (MDC track candidate)
//
//
//  this class keep information about matching between
//  inner and outer segments:
//    seg1Ind - index of inner segment (HMdcSeg object) in category.
//    seg2Ind - index of outer segment in category. 
//              If seg2Ind==-1  - no outer segments (!).
//    nCandForSeg1 - number of outer segments for this inner
//                   (for each combination exist HMdcTrkCand object).     
//                   If nCandForSeg1==0 - no outer segments               
//                   If nCandForSeg1>0 this container is first one from
//                   nCandForSeg1 objects.
//                   If nCandForSeg1==-1 - one of the next objects.
//    nextCandInd  - index of next HMdcTrkCand object.
//                   If nextCandInd==-1 this object is latest from
//                   nCandForSeg1 objects.
//   
//
//  The HMdcTrkCand objects are stored in the matrix category catMdcTrkCand.
//
//  Retrieving of HMdcTrkCand objects.
//    Let pMdcTrkCandCat is poiner to catMdcTrkCand category
//    and iterMdcTrkCand is corresponding iterator then:
//
//    iterMdcTrkCand->Reset();
//    while( (pMdcTrkCand=(HMdcTrkCand*)iterMdcTrkCand->Next()) !=0) {
//      Short_t nOuterSeg=pMdcTrkCand->getNCandForSeg1();
//      if(nOuterSeg==0) {    // no outer segments:
//        ...           
//      } else {
//
//        //----------------------------------------------------------------
//        // If you don't care about number of outer segments for inner one:
//        ...              // your code
//
//        //----------------------------------------------------------------
//        // Otherwise:
//        if(nOuterSeg==-1) continue;
//        Short_t nextObjInd=0;
//        while (nextObjInd>=0) {
//          ...              // your code
//          // Next HMdcTrkCand object geting:
//          nextObjInd = pMdcTrkCand->getNextCandInd();
//          if(nextObjInd>=0) pMdcTrkCand = 
//              (HMdcTrkCand*)pMdcTrkCandCat->getObject(nextObjInd);
//        }
//
//      }
//    }
//--------------------------------------------------------------------------
//  dedx fom Mdc segments can beretrieved via
//  getdedxInnerSeg()         mean value of t2-t1 for inner segment
//  getdedxOuterSeg()         sigma of t2-t1 distribution in inner segment
//  getSigmadedxInnerSeg()    number of wires in inner segment
//                            before truncated mean procedure
//  getSigmadedxOuterSeg()    number of wires in inner segment
//                            cutted by truncated mean procedure
//  getNWirededxInnerSeg()    mean value of t2-t1 for outer segment
//  getNWirededxOuterSeg()    sigma of t2-t1 distribution in outer segment
//  getNWireCutdedxInnerSeg() number of wires in outer segment
//                            before truncated mean procedure
//  getNWireCutdedxOuterSeg() number of wires in outer segment
//                            cutted by truncated mean procedure
//
//  to do it inside a loop the following functions ar provided
//
//  getdedxSeg(Int_t seg)          seg==0: for inner seg , seg==1 for outer seg
