  * Sometimes you want to get access to the injector of a currently running Angular app
  * from outside Angular. Perhaps, you want to inject and compile some markup after the
  * application has been bootstrapped. You can do this using extra `injector()` added
  * to JQuery/jqLite elements. See {@link angular.element}.

  * In the following example a new block of HTML containing a `ng-controller`
  * directive is added to the end of the document body by JQuery. We then compile and link
  * it into the current AngularJS scope.
