Class Description

  Chip Tracking Trigger Engine
  ============================

  Tracking trigger built in front end chip.
  The algorithm searches for sequences of pixels (over the threshold)
  consequtive and adjacent. If the track length is over a threshold,
  trigger occurs.
  The algorithm searches also between track segments of two nearby chips:
  if two track segments are consequtive in time and the total length is
  over a threshold (different from the previous one), trigger occurs

  Parameters:

  fThresholdType: specify if the threshold on pixel hits in a gtu is absolute
                  or relative
  Valid options:
    - absolute: the value specified in fThreshold is the minimum number of hits
                in a gtu to consider
    - relative: trigger threshold depends by the mean value of the background
                hits (B) in each pixel:
           threshold = (B) + fThreshold*sqrt(B)
  fThreshold: threshold on pixel hits in a gtu; if fThresholdType=relative the
              true threshold used by trigger algorithm depends by the mean hits
              of background in each pixel (see above)
  fMinTrackLenght: min length of the valid tracks
  fMaxTrackLength: max length of the valid tracks
  fMinTriggerTrackLength: min track length to have a trigger (single chip)
  fMinTriggerTwoLength: min total track length in 2 nearby chips
  fMaxTwoLength: max track length allowed in 2 nearby chips

  fAcceptHole [bool] : an hole in a single track segment is or not accepted
  fOnlyWithSignal [bool] : processes or not only chips ith at least a signal
