public delegate void QueryProgressCallback (Entry entry, uint entry_key, uint entry_count)
Callback function called for each Entry parsed in a Feed when loading the results of a query.
It is called in the main thread, so there is no guarantee on the order in which the callbacks are executed, or whether they will be called in a timely manner. It is, however, guaranteed that they will all be called before the TaskReadyCallback which signals the completion of the query is called.
