-         *
-         * SKPaymentQueue is used to queue payments or restore purchases requests.
-         * Payments are processed serially and in-order and require user interaction.
-         * Restore purchases requests don't require user interaction and can jump ahead of the queue.
-         * SKPaymentQueue rejects multiple restore purchases calls.
-         * Having one payment queue observer for each request causes extra processing
-         * Failed transactions only ever belong to queued payment requests.
-         * restoreCompletedTransactionsFailedWithError is always called when a restore purchases request fails.
-         * paymentQueueRestoreCompletedTransactionsFinished is always called following 0 or more update transactions when a restore purchases request succeeds.
-         * A complete transactions handler is require to catch any transactions that are updated when the app is not running.
-         * Registering a complete transactions handler when the app launches ensures that any pending transactions can be cleared.
-         * If a complete transactions handler is missing, pending transactions can be mis-attributed to any new incoming payments or restore purchases.
-         *
-         * The order in which transaction updates are processed is:
-         * 1. payments (transactionState: .purchased and .failed for matching product identifiers)
-         * 2. restore purchases (transactionState: .restored, or restoreCompletedTransactionsFailedWithError, or paymentQueueRestoreCompletedTransactionsFinished)
-         * 3. complete transactions (transactionState: .purchased, .failed, .restored, .deferred)
-         * Any transactions where state == .purchasing are ignored.
