Create a class that represents a particular group of customers and the associated account executive. The class must contain at a minimum the following: an identifier for the group, an account executive of type Employee, a List of Customers belonging to the group, a default constructor, a constructor that accepts an Employee object to be used as the account executive. You may reuse the Customer class from EX1 and the Employee class from the example project. Include a test program that exercises the new class - no need to test the Customer or Employee classes, just use them. Zip the entire project folder and submit it here when complete.
