   * Use it on {@link android.content.Context} fields in an {@link EBean}
   * annotated classes to inject context of the parent class.

   * <p>
   * This field may not be injected at runtime if the context used to create the
   * bean is not of the appropriate type. For example, if you create a new
   * instance of the bean using a Service context, and you use {@link RootContext}
   * on a field that extends Activity, this field will be null at runtime.
