LogCtl (Apache Jena Base)

java.lang.Object
- org.apache.jena.atlas.logging.LogCtl

```
public class LogCtl
extends Object
```
Setup and control of logging - needs access to log4j2 binaries. Sources of configuration:
- Standard setup (e.g. for log4j2, property log4j.configurationFile
- jena-cmds: the shell scripts set logging to "apache-jena/log4j2.properties." (uses stderr)
- Default logging for log4j2: java resource src/main/resources/log4j-jena.properties (uses stdout)

  - setLogging
```
public static void setLogging()
```
    Set logging.
    Normally, the logging provider mechanism should be used. This call will insert some kind of logging set for JUL and Log4j2 when no configuration is setup; output is to stdout.
    Ideally, initialize the logging provider using the mechanism specific to that provider. For example, see the log4j2 configuration documentation.
    To set application logging, choose one of:
    - For JUL logging, have a dependency on artifact org.slf4j:slf4j-jdk14.
    - For log4j2 logging, have a dependency on artifact org.apache.logging.log4j:log4j-slf4j-impl.
