[x3d-public] Beginnings of a Dart binding/encoding!

[John Carlson]

// You can't do anything with x3d.dart yet, so I'm not showing that 
yet.  This program runs to completion, not really showing anything.

// I decided to learn Dart.  This will help me with the 
ECMAScript/TypeScript encodings, I think.

// HelloWorld.dart Dart encoding

// time for a break.  John
