 /**
 17  
  * The <code>LocaleMessageHandler</code> is essentially a merging of the Message
 18  
  * and Messages classes, since there is no good reason to have them separate. A
 19  
  * key point is that this Handler is meant to be used for application-specific
 20  
  * messages, rather than core system messages. (That's not to say it couldn't
 21  
  * eventually replace the latter, however). Note that message codes are Strings
 22  
  * here, instead of the ints in Message.
 23  
  * <p/>
 24  
  * The LocaleMessageHandler can be called directly, but is really meant to be
 25  
  * called by LocaleMessage classes as done in the examples.
 26  
  * <p/>
 27  
  * Note that this class assumes the resource bundle is in the format
 28  
  * <bundle-name>-messages and is located at the top of the jar or classes
 29  
  * directory. We can later add the ability to specify a path prefix.
