                Notes:

                    * The classes needed to complete this exercise are defined below. You do not need to alter them.

                        * You have an Organization class, Office, Employee and various IssuedItems.

​

                Business rules:

                    * An organization has offices. 

                    * In this exercise, the organization created, "X Corp", has 2 offices, each with 5 employees. 

                    * One office is a 'virtual' office and the other is a 'brick and morter' office.

​

                Your task:

                    * You need to issue items to the employees of both offices.

                        * Employees of the brick and morter office need a face mask and hand sanitizer.

                        * Employees of the virtual office need a laptop computer.

                    * After you have issued the required items to all the employees, management needs a report.

                        * Write one line to the console for each employee containing:

                            * Organization name, Office name, Employee name, IssuedItem description.

                            * BONUS: If the IssuedItem is a LaptopComputer, also write the info for the LaptopBag that comes with the Laptop.
