The `order-processor` console app starts and manages the `order_processing_workflow`, which simulates purchasing items from a store. The workflow consists of five unique workflow activities, or tasks:
- `notify_activity`: Utilizes a logger to print out messages throughout the workflow. These messages notify you when:
- You have insufficient inventory
- Your payment couldn't be processed, etc.
- You have insufficient inventory
- Your payment couldn't be processed, etc.
- `process_payment_activity`: Processes and authorizes the payment.
- `verify_inventory_activity`: Checks the state store to ensure there is enough inventory present for purchase.
