/*
Default template driver for JS/CC generated parsers running as
browser-based JavaScript/ECMAScript applications.
WARNING: This parser template will not run as console and has lesser
features for debugging than the console derivates for the
various JavaScript platforms.
Features:
- Parser trace messages
- Integrated panic-mode error recovery
