macro to generate gain and ped files

/*

DAcase2.c

This program connects to the DAQ data source passed as argument
and populates local "./result.txt" file with the ids of events received
during the run.

The program exits when being asked to shut down (daqDA_checkshutdown)
or End of Run event.

Messages on stdout are exported to DAQ log system.
