1. Redesign the TicketCounterClass to implement a generic simulation class from which a user can derive their own simulation classes.

2. Design, implement, and test a computer program to simulate the checkout at a grocery store. Your simulation must allow for multiple checkout lines and allow customers at the end of a line to move to another checkout line. This simulation differs from the one described in the chapter. For this simulation, you will have to accommodate the multiple checkout lines, decide how a customer chooses a line, and decide if and when a customer moves to a new checkout line.
