A skeleton Angular 2 app built with Babel and Browserify. Back in the time of angular2 alpha.18, angular/quickstart provided us to try Angular 2 app with on-the-fly transpilation and lazy-loading, which resulted in long waiting time for each file change. Also, I was not familiar with the Traceur tool stack and its output. angular2 npm package said The files under /es6 are es6 compatible files that can be transpiled to es5 using any transpiler. So I gave it a shot.
