/**
 * 
 * Wraps a Log4j Logger.  This non-public class is the one actually interacting
 * with the log4j.jar library.  That way LogWrapper can safely attempt to use
 * log4j.jar, but still degrade gracefully and provide logging via standard-out
 * even if log4j is unavailable.
 * 
 * The interactions with log4j.jar could be done directly inside LogWrapper
 * as long as the Java code is compiled by Java 1.4 or greater (still works
 * at runtime in Java 1.3).  The interactions with log4j.jar only need to be
 * pushed out into a separate class like this for people using a Java 1.3
 * compiler, which creates bytecode that is more strict with depedency
 * checking.
