Now that we fleshed out the notion of what a customer is, it is easier to create more than one. In fact for this task we already made an array of multiple customers.

Model

In our model we now have an array with different customers to be served. But we now have to handle the case, where the cashier gets a new customer. For that we added a new state STATE_ready_for_customer

Task

Your task is to implement, that, if a customer is finished, the cashier gets a new one.
