Brief

1. Prove that parsergen can generate SQL parser
2. The result parser only knows CREATE TABLE and SELECT statements in either MySQL or SQLite syntax, nothing else. The attempt was based on retrieved table schema, SQL database as a whole can do version control. It didn't end well due to performance issues.
3. reparse will take more than an hour to generate a GLR parser but then the corresponding scanner will follow in no time.
4. The parser is generated painfully but running very smoothly.
