  - * Used to perform change detection on the whole application.
  - *
  - * This is equivalent to `detectChanges`, but invoked on root component. Additionally, `tick`
  - * executes lifecycle hooks and conditionally checks components based on their
  - * `ChangeDetectionStrategy` and dirtiness.
  - *
  - * The preferred way to trigger change detection is to call `markDirty`. `markDirty` internally
  - * schedules `tick` using a scheduler in order to coalesce multiple `markDirty` calls into a
  - * single change detection run. By default, the scheduler is `requestAnimationFrame`, but can
  - * be changed when calling `renderComponent` and providing the `scheduler` option.
