16   * A <code>ConfigurationBuilder</code> is used to configure a Mule instance,

18   * to configure a single mule instance with each ConfigurationBuilder doing one of
19   * more of the following:
20   * <li> Creation of mule runtime artifacts (endpoint's, connector's, service's,
21   * transformer's) which are then registered with the <code>Registy</code 
22   * <li> Creation and registration of SecurityManager / TransactionManager / TransactionManagerFactory / QueueManager
23   * and ThreadingProfile's.  Unlike the runtime artifacts mule only uses a single instance of each of these and so if 
24   * multiple configuration builder create and register these artifacts only one will be used.
25   * <li> Configuration of existing Mule configuration related artifacts such as <code>MuleConfiguration</code> and 
26   * <code>ServerNotificationManager</code>
27   * <br/><br/>
28   * Which of the above takes place, depends on what the configuration source contains and the ConfgurationBuilder implementation is used.
