/**
 * A wizard node acts a placeholder for a real wizard in a wizard 
 * selection page. It is done in such a way that the actual creation
 * of a wizard can be deferred until the wizard is really needed.
 * <p>
 * When a wizard node comes into existence, its wizard may or may
 * not have been created yet; <code>isContentCreated</code> can
 * be used to determine which. A node may be asked for its wizard
 * using <code>getWizard</code>, which will force it to be created
 * if required. Once the client is done with a wizard node, its
 * <code>dispose</code>method must be called to free up the wizard;
 * once disposes, the node should no longer be used.
 * </p>
 * <p>
 * This interface should be implemented by clients wishing to
 * support this kind of wizard placeholder in a wizard selection page.
