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

* Example :
*
* <pre>
* @EBean
* public class MyClass {
*
* @RootContext
* Context context;
*
* // Only injected if the root context is an activity
* @RootContext
* Activity activity;
*
* // Only injected if the root context is a service
* @RootContext
* Service service;
*
* // Only injected if the root context is an instance of MyActivity
* @RootContext
* MyActivity myActivity;
*
* @RootContext
* void singleInjection(Context context) {
* // do stuff
