This module is a local storage database adapter for crudlet - a library that makes it easy to persist data through multiple transports.

Features

• offline-mode - enable users to browse your application without an API (assuming there's local data)
• faster initial load times - great for mobile devices
• can be used with other database transports such as crudlet-http
• cascades operations to other transports
