Class Description

  Signal 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

  Only the pure signal is processed by this trigger engine

  Parameters:

  fThreshold: threshold on pixel hits in a gtu
  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

  Special multiple configuration:
  The alorithm counts the numebr of tracks of the various trigger lengths,
  fill a specific trigger word and dump the numbers of the recognized tracks
