TPCCEda.cxx - calibration algorithm for TPC Central Electrode events

10/06/2007  sylvain.chapeland@cern.ch :  first version - clean skeleton based on DAQ DA case1
06/12/2007  haavard.helstrup@cern.ch  :  created CE DA based on pulser code
19/09/2008  J.Wiechula@gsi.de:           Added support for configuration files.

contact: marian.ivanov@cern.ch


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).
