In-process kit change

[Deanna Hood]

Functionality is there to send an order that interrupts another, but we also have to think about what is in that order. The parts that are in the interrupting kit will impact the difficulty of the second order: for example, the team may need to remove existing parts from the tray.

[Brian Gerkey]

Need to add the ability to trigger order generation based on the status of parts in a tray (e.g., poll the contents of the tray and wait until a part is in the tray, then trigger the new order).

Need to extend triggering logic to check that the tray contains a part that is not needed in the new order (to force the user to remove that part to continue).

Need to extend the scenario syntax to allow specification of this.
