class HPidTofRec: public HReconstructor

_HADES_CLASS_DESCRIPTION

 HPidTofRec
 In case of experiments where there exists no start hit and the TOF of the
 particles has to be recalculated. This class will reconstruct it,
 and the new value (plus the new beta and new mass2), will be written inside HPidTrackData
 To mark those objects as changed one can ask to HPidTrackData::getTofRecFlag(algorythm).
 The result should be 1 or 2 depending on the method which has been used, -1 if the
 reconstructor failed (such as in cases when there are only positive charged tracks and no
 leptons), 0 (default value) if the reconstructor did not run.
 If the start time reconstruction was done starting from a TOFINO track with multiplicity>1
 then the Flag will be 10 for lepton ID, 20 for pi- ID-
 Anyhow the original tof can be retrieved direct HPidHitData::getTof().

 To setup the constructor  call HPidTofRec(Text_t *name,Text_t *title, const Char_t *select, const Char_t *track),
 where "select" contains the key words for configuration (just "," separated list)
    nospline   : switch off spline
    nohires    : switch off high resolution kickplane
    nolowres   : switch off low  resolution kickplane
    nork       : switch off Runge Kutta tracking
    noreft     : switch off Reference Trajectories tracking
    norich     : switch off rich mode
    ntuple     : switch on create,fill and write ntuple for debugging
    chiin      : switch on the chi2>-1 cut for inner MDC segments
    chiout     : switch on the chi2>-1 cut for outer MDC segments
    common     : use spline as reconstructor for all the trackings
    skip       : skip event in DST if start is not reconstructed
    sim        : switch on simulation mode
    nopidparam : do not get rich parameters from HPidAlgStandCutsPar
    startrk    : catStartHit will be filled from RK
    startspline: catStartHit will be filled from SPLINE

 if common mode is switched on, "track" is the chosen tracking algorythm for global tof reconstruction:
    spline     : spline
    lowres     : low resolution kickplane
    hires      : high resolution kickplane
    rk         : Runge Kutta tracking
    reft       : Reference Trajectories tracking

 defaults (empty string) are:
   spline                      ON
   low  resolution kickplane   ON
   high resolution kickplane   ON
   RungeKutta                  ON
   Reference Trajectories      ON
   fRichMode                   ON
   ntuple                      OFF
   chi cut (inner MDC) mode    OFF
   chi cut (outer MDC) mode    OFF
   skip event                  OFF
   common                      OFF
   simulation                  OFF
   pidparam                    ON
   startrk                     ON
   startspline                 OFF

 Usage:

   HPidTofRec *pidtofrec = new HPidTofRec("tofreconstructor","tofreconstructor",option,track);
   pidtofrec->setQualityRichParams(200.,4.,2.8,5);
   HTaskSet * pidtofrectask = new HTaskSet("","");
   pidtofrectask->connect(pidtofrec);
   masterTaskSet->add(pidtofrec);
