gingersnap-0.3.1.0: Consistent and safe JSON APIs with snap-core and (by default) postgresql-simple

Straightforward JSON API tools and idioms for snap-core and datastore access (by default PostgreSQL via postgresql-simple), that provide:

• Safe access to pools of DB connections (preventing connection leaks)
• Simple and consistent JSON responses for successes and failures (including unexpected failures)
• An optional read-only/maintenance mode for keeping services up during e.g. database migrations

See the README for a tutorial and example use.
