Begins a transaction synchronously where `NSManagedObject` creates, updates, and deletes can be made.
- parameter closure: the block where creates, updates, and deletes can be made to the transaction. Transaction blocks are executed serially in a background queue, and all changes are made from a concurrent `NSManagedObjectContext`.
- returns: a `CSSaveResult` value indicating success or failure, or `nil` if the transaction was not comitted synchronously
- parameter error: the `CSError` pointer that indicates the reason in case of an failure
- returns: `YES` if the commit succeeded, `NO` if the commit failed. If `NO`, the `error` argument will hold error information.
