Title: Ability to unregister the observer for the store

If the helu store object is used in viewDidLoad as in the example, and that view is then released - then you will have messages sent to a non-existing Helu store because you did not unregister.

This piece of code should actually also come with a modification to the manual, that if your code ever throws out the Helu object, it better also close the store before doing so.
