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.
