// In case of experiments where there exists no start hit and the TOF of the
// particles has to be recalculated, the tof variable(getTof()) of all classes derived from
// HBaseTrack will be overwritten by a reconstructor which recalculates the tof.
// To mark those objects as changed one can ask with getFlag(). The result should be
// 1 or 2 depending on the method which has been used and 0 if it has not been changed.
// Anyhow the original tof can be retrieved direct from the HMdcTofHit referenced by
// tofindex (getTofHitInd()). The flag itself is decoded in the tofindex, but will be
// hidden from the user by the getTofHitInd() function.
