closes #741

Add an example app to the labs for AngularDart without routing.

AngularDart is heavily inspired by AngularJS and is supercharged for Dart. Core
Angular features such as directives, data binding, and dependency injection, are

and classes to feel natural for Dart developers. AngularDart is also the first
version of Angular to be built on emerging web standards like Shadow DOM.
