Chapter 9, Inheritance and statemachines

265 Remove the 20pixel marging on the buttons and apply Align Items property End instead to make everything end up at the bottom line

286 Add a transition from InOwnershipTransaction to OwnershipStable, name the trigger CloseSale

287 Add a transition from OwnershipStable to InOwnershipTransaction, reuse the trigger InitiateSale on this transition

298 Save and test on the web, Create a CarFactory, call it BWM in Munich, Add a Car to this CarFactory
