Detailed Description

Manages the subscription to events from an AsyncEventSource.

Removes the associated listener automatically on destruction.

The Scope is usually placed as a member in the subscribing object. Unsubscribe should be called manually in the objects destructor, before anything that the callback needs is destroyed.
