Your assignment this afternoon is to design the Action classes
                        for both the Customer and World Appls


                  4) Define the Action Classes
                      list the routines (functions/methods/actions)
                       each class should have (implement)
                       this is an Interface (a list of methods)
                      write and test each routine (method)
                      
                   Go back thru the ProjectOverview and pick out the 
                   Database calls
                   
                    I think I need a DAO (Data Access Object) class to hold
                    all the SQL for Customer objects
                    
                    CustomerDAO (an Interface) any code that return Customer objects go here
                       findCustomerByName()
                       findAllCustomers()
                       
                       
                    OrderDAO any code that return Order objects go here
                       findOrderByCustomer()
                       findOrderByDate()
                       ???
