// AliTrackMap.cxx
// description: 
//   contains a relation between track label and it's index
//   in a TreeH.
//   The main method is At, it takes a particle label as an argument
//   and returns the correponding entry in TreeH (many particles
//   are usually stored in 1 TreeH entry, one has to check particle
//   labels for each hit). 'At' returns:
//       kNoEntry = -1 if the particle has no entry in TreeH
//       kOutOfBounds = -2 if the particle label is out of bounds
//
