/**
* An error thrown if application changes model breaking the top-down data flow.
*
* This exception is only thrown in dev mode.
*
* <!-- TODO: Add a link once the dev mode option is configurable -->
*
* ### Example
*
* ```typescript
* @Component({
* selector: 'parent',
* template: `
* <child [prop]="parentProp"></child>
* `,
* directives: [forwardRef(() => Child)]
* })
* class Parent {
* parentProp = "init";
* }
*
* @Directive({selector: 'child', inputs: ['prop']})
* class Child {
* constructor(public parent: Parent) {}
*
* set prop(v) {
* // this updates the parent property, which is disallowed during change detection
* // this will result in ExpressionChangedAfterItHasBeenCheckedException
* this.parent.parentProp = "updated";
* }
* }
* ```

/**
* Thrown when an expression evaluation raises an exception.
*
* This error wraps the original exception to attach additional contextual information that can
* be useful for debugging.
*
* ### Example ([live demo](http://plnkr.co/edit/2Kywoz?p=preview))
*
* ```typescript
* @Directive({selector: 'child', inputs: ['prop']})
* class Child {
* prop;
* }
*
* @Component({
* selector: 'app',
* template: `
* <child [prop]="field.first"></child>
* `,
* directives: [Child]
* })
* class App {
* field = null;
* }
*
* bootstrap(App);
* ```
*
* You can access the original exception and stack through the `originalException` and
* `originalStack` properties.
