Implement the code for a supermarket checkout that calculates the total price of a number of items. Products can be scanned and at the end a receipt be printed.

1. A product at a time can be scanned. Customer can see a subtotal which shows just the total of all scanned products.
2. Checkout can print a receipt which contains the Product and the price.
3. Multiple products of one type can be scanned, i.e two milks at once.
4. Products can have a price per weight i.e. apples with costs 2.50€/kg.
5. Discount: if a customer buys 2 bottles of milk they get the two for the price of one
6. Discount: if a customer buys 5 bars of chocolate they receive a discount of 10% for the total price of the chocolates

Example products:

Stefan Tilkov: Was ist mit Vollständigkeit? Ist es wichtig, dass ich alles dokumentiert habe? 
Wie detailliert muss denn Architekturdokumentation sein?

Gernot Starke: Das ist total überbewertet. Ich bekomme die Krise, wenn mir jemand sagt: 
„Ich will vollständige Dokumentation haben.” Das ist dieser 70er und 80er Jahre 
Ansatz – „Ich kann die gesamten Daten eines Unternehmens alle genau modellieren” - welch ein Blödsinn. 
Niemals kann ich das machen. Ich will keine vollständige Dokumentation, 
sondern relevante, aktuelle und verständliche haben. Das ist mir viel wichtiger als vollständig.
