Write a class named RetailItem that holds data about an item in a retail store. The class should store the following data in attributes: item description,
units in inventory, and price. Once you have written the class, write a program that creates three RetailItem objects and keeps them stored in a list. The
RetailItem objects should store the following data in them:

        Description   Units_in_Inventory     Price
Item #1  Jacket          12                 59.95
Item #2  Designer Jeans  40                 34.95
Item #3  Shirt           20                 24.95
Item #4  Socks           34                 14.55
Item #5  Tuxedo          7                  184.22
Item #6  Dress           17                 42.85


Next create a CashRegister class that can be used with the RetailItem class. The CashRegister class should be able to internally keep a list of RetailItem objects.
The class should have the following methods:

- A method named scan_item that accepts a RetailItem object as an argument. Each time the purchase_item method is called, the RetailItem object that is passed
as an argument should be added to the internal list.

- A method named get_total that returns the total price of all the RetailItem objects currently stored in the CashRegister object’s internal list.

- A method named show_items that neatly displays data about all the current RetailItem objects stored in the CashRegister object’s internal list.

- A method named purchase that should first call show_items, then display the result from get_total. It should then clear the CashRegister object’s internal list
by removing the object and decreasing the Units_in_Inventory by 1.

Demonstrate the CashRegister class in a program that allows the user to repeadadly select several items for purchase. When the user is ready to check
out, the program should call purchase in order to display a list of all the items he or she has selected for purchase, the total price, and correctly update
the inventory of the items.

Write an Employee class that keeps data attributes for the following pieces of information:
Employee name
Employee ID number
Hourly Pay
Hours Worked
And a method called pay_day that returns the hourly pay * hours worked and sets hours worked back to zero

Next, write a class named ShiftWorker that is a subclass of the Employee class. The ShiftWorker class should keep data attributes for the
following information:
Shift number (an integer, such as 1, 2, or 3)
Vacation Hours
Sick Hours
An updated method pay_day that uses its inherited one and also adds (vacation hours + sick hours) * hourly pay before returning

Next, write a class named ShiftSupervisor that is a subclass of the ShiftWorker class. The ShiftSupervisor class should keep data attributes for the
following information:
Bonus
An updated method pay_day that uses its inherited one and also adds the bonus before returning


Demonstrate these class by writing a program that creates an Employee, a ShiftWorker, and a ShiftSupervisor. Show them working correctly by calling each of
their pay_day functions and printing the result next to the expected result for example, the result for an Employee with 40 hours worked and an hourly pay
of 15 should look like this:

Expected payday : 600.00
Running payday function . . .
#Run payday function now, then print result
Returned payday : 600.00
