TPCQAda.cxx - algorithm for TPC RAW QA

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
09/06/2008  peter.christiansen@hep.lu.se and haavard.helstrup@cern.ch  :  created QA DA based on AliTPCdataQA code

10/09/2009  Jens.Wiechula@cern.ch:     Export object to AMOREdb after a defined update interval for QA
26/01/2010  Jens.Wiechula@cern.ch:     Exclude laser triggers when running in a global partition

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).
