TPCda_pedestal.cxx - calibration algorithm for TPC pedestal runs

10/06/2007  sylvain.chapeland@cern.ch :  first version - clean skeleton based on DAQ DA case1
19/10/2007  christian.lippmann@cern.ch :  Possibility to write output to ASCII file
24/10/2007  christian.lippmann@cern.ch :  Including pedestal calibration for time bins
23/11/2007  christian.lippmann@cern.ch :  Fix in order to avoid streamer problems in case of
                                          invalid ROOTSTYS. The famous magic line provided by Rene.
28/11/2007  christian.lippmann@cern.ch :  TPC mapping file is read from DaqDetDB
18/09/2008  christian.lippmann@cern.ch :  Noisy channels are output to ASCII file. Use max noise in ALTRO.
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).
