///////////////////////////////////////////////////////////////////////////////
// HMdcRaw
//
// Unpacked raw data of the MDC
//
// In measurement mode the TDC accepts two hits per channel. The TDC can hereby
// trigger either on two leading edges (hit multiplicity nHits: -1 or -2) or
// on a leading and the trailing edge of a single pulse (nHits: +1 or +2).
// The TDC is able to generate internal calibration events. In this case a
// single channel sends 6 time informations (nHits: +6).
//
// The addresses of the cell can be accessed via the inline functions
//     void setSector(const Int_t n)
//     void setModule(const Int_t n)
//     void setMbo(const Int_t n)
//     void setTdc(const Int_t n)
//     void setAddress(const Int_t sector,const Int_t module,const Int_t mbo,
//                     const Int_t tdc)
//     Int_t getSector(void) const
//     Int_t getModule(void) const
//     Int_t getMbo(void) const
//     Int_t getTdc(void) const
//     void getAddress(Int_t& sector,Int_t& module,Int_t& mbo,Int_t& tdc)
// and the number of hits with the inline function
//     Int_t getNHits(void) const
//
// The inline function clear() sets the data data members to the following
// values:
//          nHits=0;
//          sector=module=mbo=tdc=-1;
//          time1=time2=time3=time4=time5=time6=-999;
