/**
* Does the localization of texts.
* <p>
* Each class that uses String that reach the user interface has its own
* Localizer. You can get a localized String by using one of the msg methods.
* <p>
* The msg methods have all the same pattern:<br>
* <code>String msg(key, defaultValue, [args]);</code>
* <ul>
* <li>The <CODE>key</CODE> is a String that identifies the message. Each class
* has its own namespace.</li>
* <li>The defaultValue is the value you would expect on an English system. (But
* note: Even on an English system you may get a different String!)</li>
* <li>The optional <CODE>args</CODE> are arguments that will be parsed into the
* message. See {@link java.text.MessageFormat} for details.
* </li>
* </ul>
