TPCda_pulser.cxx - calibration algorithm for TPC pulser events

10/06/2007  sylvain.chapeland@cern.ch :  first version - clean skeleton based on DAQ DA case1
30/09/2007  haavard.helstrup@cern.ch  :  created pulser DA based on pedestal code
19/09/2008  J.Wiechula@gsi.de:            Added export of the calibration data to the AMORE data base.
                                          Added support for configuration files.

This process reads RAW data from the files provided as command line arguments
and save results in a file (named from RESULT_FILE define - see below).
