Remove shorthand to create new child context without specified concurrency type. Doesn't save a lot of typing and decreases clarity since it's not clear which type will be used as default
Remove persistentStoreCoordinator access again, no need to have a shorthand here
Possibility to manually reset FetchedResultsController updater
Add method to retreive the count of objects matching a fetch request
