      With those cautions in mind, what are we doing in this QuickStart configuration?
  
      First, we create a map to tell SystemJS where to look when we import some module.
      Then, we register all our packages to SystemJS: 
      all the project dependencies and our application package, `app`.

        Our QuickStart doesn't use all of the listed packages 
        but any substantial application will want many of them
        and all of the listed packages are required by at least one of the documentation samples.
        
        There is no runtime harm in listing packages that we don't need as they will only be loaded when requested.

      The `app` package tells SystemJS what to do when it sees a request for a 
      module from the `app/` folder.
