Implementing scatter gather

We're going to use the start orchestration shape to process all of these requests in true parallel. This pattern is commonly referred to as scatter-gather because we scatter the requests out and then gather the responses back together. To do this we will use a self-correlating direct bound port and another orchestration. First we will add this new port to the ReorderCalculations orchestration:

1. In ReorderCalculations.odx drag a new port to the port canvas.
2. Name the port Receive_DirectCalculationPort and create a new port type named DirectCalculationPortType.
3. Set the binding to Direct and choose the Self Correlating radio button.
4. Rename Operation_1 to ProcessCalculation and set the Message Type of the request to PRP.InventoryManagement.Orchestrations.InventoryNotificationType ...
