 Logging

-Calimero uses the [Simple Logging Facade for Java (slf4j)](http://www.slf4j.org/). Users can bind any desired logging frameworks. The default maven dependency is the [Simple Logger](http://www.slf4j.org/api/org/slf4j/impl/SimpleLogger.html). The simple logger logs everything to standard output, and can be configured via the file `simplelogger.properties`, JVM system properties, or `java` command line options, e.g., `-Dorg.slf4j.simpleLogger.defaultLogLevel=warn`.
