                * The classes needed to complete this exercise are defined below.

            Business rules:

                * An organization has employees.

                * Some employees are hourly employees.

                * Some employees are salaried employees. 

                * All salaried employees have a computer. Some have desktop computers. Some have laptop computers.

            Your task is to write information for each employee to the console. Examples:

                * If an employee is an hourly employee, write "HourlyEmployee".

                * If an employee is a salaried employee with a desktop computer write "SalariedEmployee with DesktopComputer".

                * If an employee is a salaried employee with a laptop computer write "SalariedEmployee with LaptopComputer".
