17   * Enables Mule annotation processing so that annotated objects registered with the Mule registry will automatically
18   * be configured. This helper also enables JSR-330 injection annotations {@link javax.inject.Inject} and {@link javax.inject.Named}.
19   * <p/>
20   * Internal Implementation note: We could have used a 'registry-bootstrap.properties' file to load the objects necessary
21   * to enable annotations however, that method would not allow the annotation processors to be easily overridden when using
22   * other platforms such as Google App Engine.
