/**
 * Represents a User for GeoServer.
 *
 * <p>
 * Used as a typesafe Session container. This is an alternative to using calls
 * to request.getAttributes( key ) and casting.
 * </p>
 *
 * <p>
 * The User object is saved in session scope by ConfigAction:
 * </p>
 * <pre><code>
 * HttpSession session = request.getSession();
 * User user = request.getAttributes( UserContainer.WEB_CONTAINER_KEY );
 * if( user == null ){
 *     user = new UserContainer( request.getLocal() );
 *     session.setAttributes( UserContainer.WEB_CONTAINER_KEY, user );
 * }
 * </code></pre>
 *
 * <p>
 * This class is based on the UserContainer class outlined in the book
 * "Programming Jakarta Struts" by Chuck Cavaness.
