ChangeDetectorRef class
Provides influence over how change detection should execute for a component.
In practice, this is often used just for markForCheck, which sets a
component that uses ChangeDetectionStrategy.OnPush as dirty for future
change detection.
NOTE: This API is currently transitional. Please use carefully, and
avoid methods that are marked @Deprecated(...), as they will be eventually
removed entirely.
