v2.0.0

Re-released without a direct dependency on package:analyzer!

For users of the 1.x branch of code_builder, this is a pretty big breaking
change but ultimately is for the better - it's easier to evolve this library
now and even add your own builders on top of the library.

void main() {
  final animal = new Class((b) => b
    ..name = 'Animal'
    ..extend = refer('Organism')
    ..methods.add(new Method.returnsVoid((b) => b
      ..name = 'eat'
      ..lambda = true
      ..body = const Code('print(\'Yum\')'))));
  final emitter = new DartEmitter();
  print(new DartFormatter().format('${animal.accept(emitter)}'));
}

...outputs...

class Animal extends Organism {
  void eat() => print('Yum!');
}

Major changes:

• Builders now use built_value, and have a more consistent, friendly API.
• Builders are now consistent - they don't any work until code is emitted.
• It's possible to overwrite the built-in code emitting, formatting, etc by
  providing your own visitors. See DartEmitter as an example of the built-in
  visitor/emitter.
• Most of the expression and statement level helpers were removed; in practice
  they were difficult to write and maintain, and many users commonly asked for
  opt-out type APIs. See the Code example below:

void main() {
  var code = new Code('x + y = z');
  code.expression;
  code.statement;
}

and avoid breaking changes, suggestions, new features, and incremental updates
are welcome!
