/**
* A collection of the Angular core directives that are likely to be used in each and every Angular
* application.
*
* This collection can be used to quickly enumerate all the built-in directives in the `@View`
* annotation. For example,
* instead of writing:
*
* ```
* import {If, NgFor, NgSwitch, NgSwitchWhen, NgSwitchDefault} from 'angular2/angular2';
* import {OtherDirective} from 'myDirectives';
*
* @Component({
* selector: 'my-component'
* })
* @View({
* templateUrl: 'myComponent.html',
* directives: [If, NgFor, NgSwitch, NgSwitchWhen, NgSwitchDefault, OtherDirective]
* })
* export class MyComponent {
* ...
* }
* ```
* one could enumerate all the core directives at once:
*
* ```
* import {coreDirectives} from 'angular2/angular2';
* import {OtherDirective} from 'myDirectives';
*
* @Component({
* selector: 'my-component'
* })
* @View({
* templateUrl: 'myComponent.html',
* directives: [coreDirectives, OtherDirective]
* })
* export class MyComponent {
* ...
* }
* ```
*
