CI / test (push) Successful in 50s
Add the Menu, MenuItem, CoffeeMaker and MoneyMachine classes with the assignment's method names, and a main loop that supports drink names, report and off. Resources are checked before payment, and payment before the drink is made. Move drink prices, ingredient amounts and all message text into constants.py. Add 25 pytest tests for every class and the main loop, and record the review against QC-PY-001 as RC-007.
