actually, for polymer we only need to apply the observe transformer on a single
file. Could we specify that instead?

In other words, we want something that matches this part of polymer's pubspec:

transformers:
- observe:
    files: lib/src/instance.dart

Updated builder & deploy to cover this.

awesome, thanks!

   return runBarback(barbackOptions)
       .then((_) => print('Done! All files written to "${options.outDir}"'));
 }
