== Example Configuration for Logging Logic

The following example shows a configuration that logs policy logic to standard out (__info__) and a file (__debug__)
All other APEX components are logging to a file (__debug__) and standard out (__error__).
This configuration an be used in a pre-production phase with the APEX engine still running in a separate terminal to monitor policy execution.
This logback configuration is in the APEX installation as `etc/logback-logic.xml`
