THcTimeSyncEvtHandler is a toolbox to study and correct various
  synchronization issues.
  It checks that the timestamp in the FADC250s agrees with the timestamp
  in the TI modules.
  It also checks if the event counter in the 1190 modules agrees with the
  event counter in the TI modules.
  It can be used to correct the 1190 synchronization problem we have
  seen in ROC3 by writing out a corrected data file.  See the next commit
  for an example of how it is used.
