Class Description

      This is the persistent storage class for DrcPidInfo objects.

      This interface requires the following functions for interactive access:
      // These functions apply to the various PID hypothesis
           UInt_t nHypos() const                       // number of hypos stored for this ring
           Double_t nExPhotons(Pdt::Pid pid) const     // # of photons expected for hypo
           Double_t consistency(Pdt::Pid pid) const    // consistency with hypo
           Double_t likelihood(Pdt::Pid pid) const     // likilihood of hypo
      // These functions are defined for the ring as a whole.
           Double_t thetaC() const;     // Cerenkov angle
           Double_t thetaCErr() const;  // Error on Cerenkov angle
           Double_t momentum() const;   // Momentum at the DiRC
           UInt_t nHit() const          // Number of hits in the ring
           UInt_t nBkg() const          // Number of background hits in the ring

      Additionally, this interface requires two functions which are used in
      transient-persistent-transient conversion:

           void setTrkRecoTrkI(const TrkRecoTrkI*);  // Cache the associated track
           const TrkRecoTrkI*  trkRecoTrkI() const;  // Return the associated track

      These functions are called when rebuilding the PidSummary objects.

      Persistent Location:
        Aod::"Pid_DrcPids"

      Persistent Size: 48 Bytes per object (unpacked)
      Structure:

            // DrcTrack data
            Char_t _nhypos;            // slways 5
            Char_t _alg;               // Algorithm ID
            UShort_t _thetac;          // Cerenkov angle packed flat from 0. - 1.
            UShort_t _ethetac;         // Eerror on Cerenkov Angle packed flat from 0. - 0.1
            UShort_t _index;           // Not really sure. . .
            UShort_t _statusDRC;       // .. what these two are meant to be
            UShort_t _momentum;        // Momentum at the DiRC packed flat from 0. - 8. (15 bits)
            Char_t _nhit;              // Number of hits in Cerenkov Ring
            Char_t _nbkg;              // Number of background

            // Hypo data
            UShort_t _nexphot[5];      // Number of expeceted photons for each PID hypothesis
            UShort_t _consistency[5];  // Consistency for each PID hypothesis
            UShort_t _likelihood[5];   // Likelihood for each PID hypothesis
