Add logLevel property to enable different log levels for the examples.Motivation:When running the examples using the provided run-examples.sh script thelog level is 'info' level. It can be handy to be able to configure adifferent level, for example 'debug', while learning and trying out thethe examples.Modifications:Added a dependency to logback-classic to the examples pom.xml, and alsoadded a logback configuration file. The log level can be configured bysetting the 'logLevel' system property, and if that property is not setthe default will be 'info' level.The run-examples.sh was updated to show an example of using the systemproperty to set the log level to 'debug'Result:It is now possible to turn on debug logging by settnig a system propertyon the command line.
