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