class HDstProduction: public TObject

 Default Constructor: gHades created, Root set to batch mode.

 First this function checks on the command line, weather a
 configuration file was specified. Then these information
 are evaluated, before the command line is search again for
 other option.

 This means, that the program parameter are evaluated in the
 following order of precedence (low to high):
   1. Default parameter from constructor
   2. Parameter read from configuration file
   3. Parameter read from command line

 Setup the spectormeter. This functions creates the setup of the
 spectrometer using the related module parameters of the dstCfg
 structure.

 Setup and open parameter sources. The function uses the related variables
 of the dstCfg structure to decide which source is taken.

 Setup data input file: This function determines and opens
 one or more .root input files of analysed data. All necessary
 information are provided by dstCfg structure.

 Setup data output: This function opens a .root output file, those
 name is derived from the input filename and initializes the output
 tree 'T' in this file.
 CAUTION: This function must be called AFTER initialize(), otherwise
 the output is corrupted or the program might crash.

 Dump all parameter of an experiment to an .root output file.
 This function expects a filename ending on '.root' in dstCfg parameter
 structure, if the output should be written to a Root file.
 Actually to dump the parameter to file one has to destroy the object
 gHades after the event loop was executed, thus do:
    setupAllParameterOutput();
    initialize();
    runEventLoop();
    finalize();

 Dump the used parameter to an .root output file.
 This function expects a filename ending on '.root' in dstCfg parameter
 structure, if the output should be written to a Root file.
 Actually to dump the parameter to file one has to destroy the object
 gHades after the event loop was executed, thus do:
    setupParameterOutput();
    initialize();
    runEventLoop();
    finalize();

 Just print the content of the dstCfg structure.

 Just initialize the analysis run.

 Run the event loop an print the timing information of the
 executed tasks, if available.
 The number of events to be processed and other parameter
 are provided by the dstCfg structure.

 Close all IO sources and exit the program successfully.

 Write parameters to the output file. If setupAllParameterOutput()
 was used to set the name of the output parameter file,
 parameters for the whole beamtime period are written.
 In the case of using setupParameterOutput() function,
 parameters only for a single runID are written.

 At the end close all IO sources and exit the program with an error code.

 Just print the help on the command line options.
