 * $Log: StTrsZeroSuppressedReader.cc,v $
 * Revision 1.14  2008/06/20 15:01:21  fisyak
 * move from StTrsData to StTpcRawData
 *
 * Revision 1.13  2005/09/09 22:12:49  perev

 * Add (GEANT) track Id information in Trs; propagate it via St_tpcdaq_Maker; account interface change in StTrsZeroSuppressedReaded in StMixerMaker
 *
 * Revision 1.9  2003/09/19 22:17:50  jecc
 * Fix bug in getSequences intruced during gcc 3.2 updates

 *
 * Revision 1.2  1999/12/08 02:10:43  calderon
 * Modified to eliminate warnings on Linux.
 *
 * Revision 1.1  1999/11/05 22:18:17  calderon
 *
 * Made private copy constructor and operator= in StTrsDigitalSector.
 * Renamed DigitalSignalGenerators: Fast -> Old, Parameterized -> Fast
 * and use new "Fast" as default.
 * Added StTrsZeroSuppressedReader and StTrsZeroSuppressedReader for DAQ type
 * data access.
 * Removed vestigial for loop in sampleAnalogSignal() method.
 * Write version of data format in .trs data file.
