BREAKING CHANGES:
Dart applications and TypeScript applications meant to transpile to Dart must now
import `package:angular2/bootstrap.dart` instead of `package:angular2/angular2.dart`
in their bootstrap code. `package:angular2/angular2.dart` no longer export the
bootstrap function. The transformer rewrites imports of `bootstrap.dart` and calls
to `bootstrap` to `bootstrap_static.dart` and `bootstrapStatic` respectively.
Enable pregenerated (for Dart) and JIT (for Js) change detectors when
possible. Previously we would always use `DynamicChangeDetector`s, but
these cause megamorphic calls and are therefore much slower.
Closes#502
To support interface-based lifecycle methods (#2220), we need to be able
to query for the `interface`s a class supports. Record implemented
interfaces to allow mirror-less querying at runtime.
Closes#2204
Add a step that reads `DirectiveMetadata` object off annotated classes
into `.ng_meta.dart` files. These will be used by the `TemplateCompiler`
step as inputs to the Angular 2 render compiler.
Update one test to avoid unsupported functionality, format others.
