 * We generate directive wrappers to prevent code bloat when a directive is used.
 * A directive wrapper encapsulates
 * the dirty checking for `@Input`, the handling of `@HostListener` / `@HostBinding`
 * and calling the lifecyclehooks `ngOnInit`, `ngOnChanges`, `ngDoCheck`.
 *
 * So far, only `@Input` and the lifecycle hooks have been implemented.
