Yes, you have to call Store.save(person) or Store.remove(person)
explicitly to tell BeanKeeper what to do. This is unlike other
persistence frameworks which "track" your objects runtime.
BeanKeeper only does something if it's told to do something. If you want
to somehow abstract BeanKeeper out of your code, you can write a good
interface and use that instead of Store with a factory pattern for example.
