  additional numeric indication of their priority called the ``debug_level`` to
  allow for different levels of verbosity.
 
  The agreed values for ``debug_level`` are
 
  * **0-9** for user code. These numbers are reserved for user analysis code and
    may not be used by any part of basf2.
  * **10-19** for analysis package code. The use case is that a user wants to debug
    problems in analysis jobs with the help of experts.
 
  * **20-29** for simulation/reconstruction code.
  * **30-39** for core framework code.

  more prominent and they should not be ignored by the user but they are not
  critical.
 
.. attribute:: ERROR
 
  For messages which indicate a clear error condition which needs to be
  recovered. If error messages are produced before event processing is started
  the processing will be aborted. During processing errors don't lead to a stop
  of the processing but still indicate a problem.

exposes the `LogConfig` class as well as the `LogLevel`

one can simply do:

consistent error reporting throughout the framework
