/**
 * Base class for all implementations of AngularJs conntrollers in GWT. To use,
 * subclass {@code AngularController} and define an onInit method taking at least one
 * {@link Scope} object. Each parameter of the onInit method is assumed to be an injectable type, either
 * a builtin type, or a custom injectable type defined by {@link NgInject}.
 * 
 * 
Any additional public methods defined will automatically be exported to the $scope object used by
 * the controller and callable from the view.
 * 

 * 
 *     public class MyController extends AngularController {
 *         public void onInit(Scope scope) {
 *             // publish key "foo" with value "bar" into $scope
 *             scope.put("foo", "bar");
 *         }
 *
 *         // automatically published as $scope.doIt
 *         public void doIt(String arg) {
 *             Window.alert(scope.getString("foo") + " " + arg);
 *         }
 *     }
 * 
 * 
 * See the documentation for {@link Scope} for how to define custom Scope subtypes with type-safe accessors.
