/**
* Logging Implementation using the SLF4J
* logging facade.
*
* Note that by design, the SLF4J facade does not ship with an actual
* implementation so that it can be chosen during runtime. If you fail to
* provide a logging implementation during runtime, no log messages will
* be logged. See the SLF4J
* Manual for more information on how to do this.
*
* Since SLF4J does not support a FATAL log level, errors logged at that
* level get promoted down to ERROR, since this is the highest level
* available.
