bistromathic - all the bells and whistles

This example demonstrates best practices when using Bison.

• Its hand-written scanner tracks locations.
• Its interface is pure.
• Its interface is "incremental", well suited for interaction: it uses the push-parser API to feed the parser with the incoming tokens.
• It features an interactive command line with completion based on the parser state, based on yyexpected_tokens.
• It uses Bison's standard catalogue for internationalization of generated messages.
• It uses a custom syntax error with location, lookahead correction and token internationalization.
• It supports debug traces with semantic values.
• It uses named references instead of the traditional $1, $2, etc.
