Detailed Description

Utilities to get the online configuration.

Code modernised and ported from
Reconstruction/RecExample/RecExOnline/python/OnlineISConfiguration.py

    Example usage from as CLI:
        python -m PyUtils.OnlineISConfig

    Example usage in python:
        from PyUtils.OnlineISConfig import GetRunType
        print(GetRunType()[1])
