CARunner.py: Use argparse, allow setting (overwriting) debug-stange, number of events and log-level
Rework the CARunner.py script (used to execute a pickled ComponentAccumulator), switch to python's argparse module.
The following properties can be set:
- log-level
- debug-stange
- max number of events
I practice, this means the values stored in the pickled ComponentAccumulator are overwritten before executing it.
