Allow admin users to change global app settings like app name, contact email.

With this gem you store settings in the database, and have a UI to change settings.

This way, developers do not have to change code and re-deploy the app when configurations change.

It's amazing that you can use Setting before Rails is initialized. Meaning, you can maybe even let admins edit API keys!
