// This is a TTask that made the calculation of the Time zero using TOF.
-// Description: The algorithm used to calculate the time zero of interaction
-// using TOF detector is the following.
-// We select in the MonteCarlo some primary particles - or tracks in the following -
-// that strike the TOF detector (the larger part are pions, kaons or protons).
-// We choose a set of 10 selected tracks, for each track You have the length
-// of the track when the TOF is reached (a standard TOF hit does not contain this
-// additional information, this is the reason why we implemented a new time zero
-// dedicated TOF hit class AliTOFhitT0; in order to store this type of hit You
-// have to use the AliTOFv4T0 as TOF class in Your Config.C. In AliTOFv4T0 the
-// StepManager was modified in order to fill the TOF hit branch with this type
-// of hits; in fact the AliTOF::AddT0Hit is called rather that the usual AliTOF::AddHit),
-// the momentum at generation (from TreeK) and the time of flight
-// given by the TOF detector.
-// (Observe that the ctor of the AliTOF class, when the AliTOFv4T0 class is used, is called
-// with the "tzero" option: it is in order create the fHits TClonesArray filled with
-// AliTOFhitT0 objects, rather than with normal AliTOFhit)
-// Then Momentum and time of flight for each track are smeared according to
-// known experimental resolution (all sources of error have been token into account).
-// Let consider now only one set of 10 tracks (the algorithm is the same for all sets).
-// Assuming the (mass) hypothesis that each track can be AUT a pion, AUT a kaon, AUT a proton,
-// we consider all the 3 at 10 possible cases.

// For each track in each (mass) configuration

-// we calculate the time zero (we know in fact the velocity of the track after
-// the assumption about its mass, the time of flight given by the TOF, and the
-// corresponding path travelled till the TOF detector). Then for each mass configuration we have
-// 10 time zero and we can calculate the ChiSquare for the current configuration using the
-// weighted mean over all 10 time zero.
-// We call the best assignment the mass configuration that gives the minimum value of the ChiSquare.
-// We plot the weighted mean over all 10 time zero for the best assignment,
-// the ChiSquare for the best assignment and the corresponding confidence level.
-// The strong assumption is the MC selection of primary particles. It will be introduced
-// in the future also some more realistic simulation about this point.
