"Query" class which sends a separate copy of its state to each watcher. See NotifierWithQuery.
Appropriate when the state is mutable (such as a Cursor), and watchers who were all trying to use it (e.g., Fragments presenting different visualizations of the same query result) could interfere with each other if they tried to share state (e.g., by one changing a Cursor's current row behind the other's back).
