Removed bad docs in Schedulers

 In this example, the method `example()` will be called every second. As you can see, the class is annotated with `@Scheduler` to indicate that the class contains scheduler tasks and every method that needs to be scheduled is annotated with `@Scheduled` accepting as a param a cron.

-Now that we have a service class to retrieve cities, let's use it inside the `CityController`:
-
-```dart
-@Controller('cities')
-class CityController {
-  final CityService _cityService;
-
-  CityController(this._cityService);
-
-  @Post()
-  void create(@Body() City city) {
-    _cityService.create(city);
-  }
-
-  @Get()
-  List<City> findAll() {
-    return _cityService.findAll();
-  }
-}
-```
-
-The `CityService` is injected through the class constructor.
-
-# Provider registration
-
-Now that we have defined a provider (`CityService`), and we have a consumer of that service (`CityController`), we
-need to
-register the service with Dartness so that it can perform the injection. We do this by editing our module file (
-app.dart) and adding the service to the `providers` attribute of the `@Application()` annotation using
-the `ModuleMetadata` class in order to structure the metadata and the  `ProviderMetadata` class to structure our
-provider.
-
-```dart
-@Application(
-  module: Module(
-    metadata: ModuleMetadata(
-      controllers: [
-        ProviderMetadata(
-          classType: CityController,
-        ),
-      ],
-      providers: [
-        ProviderMetadata(
-          classType: CityService,
-        ),
-      ],
-    ),
-  ),
-)
-class App {}
-```
-
-Dartness will now be able to resolve the dependencies of the `CityController` class.
