feat(debug): replace DebugElement with new Debug DOM Now, using `ng.probe(element)` in the browser console returns a DebugElement when in dev mode. `ComponentFixture#debugElement` also returns a new DebugElement. Breaking Change: This is a breaking change for unit tests. The API for the DebugElement has changed. Now, there is a DebugElement or DebugNode for every node in the DOM, not only nodes with an ElementRef. `componentViewChildren` is removed, and `childNodes` is a list of ElementNodes corresponding to every child in the DOM. `query` no longer takes a scope parameter, since the entire rendered DOM is included in the `childNodes`. Before: ``` componentFixture.debugElement.componentViewChildren[0]; ``` After ``` // Depending on the DOM structure of your component, the // index may have changed or the first component child // may be a sub-child. componentFixture.debugElement.children[0]; ``` Before: ``` debugElement.query(By.css('div'), Scope.all()); ``` After: ``` debugElement.query(By.css('div')); ``` Before: ``` componentFixture.debugElement.elementRef; ``` After: ``` componentFixture.elementRef; ``` 2016-01-13 21:35:21 -08:00			`debugElement.query(By.all());`
