/**
 * 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.
