/**
* @fileoverview log4js is a library to log in JavaScript in similar manner
* than in log4j for Java. The API should be nearly the same.
*
* This file contains all log4js code and is the only file required for logging.
*
* <h3>Example:</h3>
* <pre>
* var log = new Log4js.getLogger("some-category-name"); //create logger instance
* log.setLevel(Log4js.Level.TRACE); //set the Level
* log.addAppender(new ConsoleAppender(log, false)); // console that launches in new window
* // if multiple appenders are set all will log
* log.addAppender(new ConsoleAppender(log, true)); // console that is in-line in the page
* log.addAppender(new FileAppender("C:\\somefile.log")); // file appender logs to C:\\somefile.log
*
* ...
*
* //call the log
* log.trace("trace me" );
* </pre>
