The beginnings of a parser generator for labeled PEGs, using TypeScript, for TypeScript.

Right now mostly a proof of concept that generates a TypeScript parser from a parser description (an AST built from parser combinators). Uses exceptions to backtrack, and a capture model similar to the one of LPEG for extracting and building results from the input.

Builtin support for error recovery through resynchronization, right now any repetition can be a resynchronization point. The idea is that on a syntax error the input is advanced to a synchronization token (using a recovery parsing expression), and then a synchronization error is thrown that lets the parser continue on a synchronization point.
