Invoicing

[brianburridge]

This is assignment 23 and is due on Feb 09, 2015.

• Create an InvoiceItem class and an Invoice class (two classes in two separate files)
• The InvoiceItem class should have the following attributes: product_name, sale_price, quantity, tax percentage
• The invoice class should have a getter and setter for an attribute called: items to hold an array of all the InvoiceItems
• Create an instance method in Invoice that will calculate a total of all it's invoice items
• Use reject or select methods in order to remove any InvoiceItem objects that have a zero quantity
• Create an instance method in Invoice to sum up the invoice items and get a total
• Ask the user to enter in the attributes for each invoice item, hitting ENTER on product name when done
• With each invoice item entered, create the object and add it to the collection of invoice items within a single Invoice object.
• Then output each line item.
• Show a sub-total without the tax, then a line item for the tax, then the total.
• Bonus: make the invoice look like a real world invoice in the terminal
