 Sets values for the probability of each particle type (in ITS)

 Gets the probability of each particle type (in ITS)

 This function returns indices of the assgined ITS clusters

 This function encodes in the module number also the status of cluster association
 "status" can have the following values:
 1 "found" (cluster is associated),
 2 "dead" (module is dead from OCDB),
 3 "skipped" (module or layer forced to be skipped),
 4 "outinz" (track out of z acceptance),
 5 "nocls" (no clusters in the road),
 6 "norefit" (cluster rejected during refit),
 7 "deadzspd" (holes in z in SPD)
 Also given are the coordinates of the crossing point of track and module
 (in the local module ref. system)
 WARNING: THIS METHOD HAS TO BE SYNCHRONIZED WITH AliITStrackV2::GetModuleIndexInfo()!

 This function returns indices of the assgined ITS clusters

 Sets values for the probability of each particle type (in TPC)

 Gets the probability of each particle type (in TPC)

 This function returns indices of the assgined TRD clusters

 This function returns the number of TRD tracklets used in tracking
 and it fills the indices of these tracklets in the array "idx" as they
 are registered in the TRD track list.

 Caution :
   1. The idx array has to be allocated with a size >= AliESDtrack::kTRDnPlanes
   2. The idx array store not only the index but also the layer of the tracklet.
      Therefore tracks with TRD gaps contain default values for indices [-1]

 Try to relate the TPC-only track parameters to the vertex "vtx",
 if the (rough) transverse impact parameter is not bigger then "maxd".
            Magnetic field is "b" (kG).

 a) The TPC-only paramters are extapolated to the DCA to the vertex.
 b) The impact parameters and their covariance matrix are calculated.
 c) An attempt to constrain the TPC-only params to the vertex is done.
    The constrained params are returned via "cParam".

 In the case of success, the returned value is kTRUE
 otherwise, it's kFALSE)
