 - When running from the command line, the environment variable O2_RUN can be used to set the run number. It is set to 0 by default, i.e. undefined run number.
+- Updated configuration parameters:
+  - added readout.numberOfRuns: in standalone mode, number of START/STOP cycles to execute (used for testing).
