[parser] Make begin/end events always come in pairs This CL: * Changes the events so beginX and endX events always comes in pairs (though technically not right as some specific events can be beginX endY --- but in those cases it is at least documented and used in code that actually tests it). -> This entails adding some events and converting something from "beginX" to "handleX" instead. * Adds a utility that can generate an AST of sorts directly from the parser via a listener using the begin/end matching (and knowing of the specific ones that doesn't match directly). * Adds a test that checks that - at least for all tested (50,000+) files - the AST actually generate "correctly", i.e. matches up begin/ends and ends up with a single top entry "CompilationUnit". * Adds a different visualization to the parser listener events by displaying the "AST directly from the parser" in a UI that can be navigated. The visualization may not be the best, but it's certainly a stepping stone.

Optimized for UI: Develop with a programming language specialized around the needs of user interface creation
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app
Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:
Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.
Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
Dart is free and open source.
