how can i cancel in process?

[amzang]

Hello,
I've already set up car-lease-demo using your source code.
It's going very well.
I have two questions.
I've not looked into your code carefully yet.

1. in every step (create and transfer), it take too much time. why does it take so long? because of validation step or other things?
2. If a leasee wants to change a car in some reason, how can i add or modify in this process?
   In almost commercial case, return/cancel/dispute happen often.

Let me know your opinion please.
Thanks.
