The Gilded Rose Kata

Summary

This is my attempt to do Emily Bache's Gilded Rose refactoring kata in python.

Read the original kata description and requirements first.

I do not start with approval tests. I use common unit tests instead.

Tasks

1. Create a bunch of tests to verify the code's conformity to the requirements. 🌹
2. Refactor the original code to make it maintainable. 🌹
3. Create another test for the new item type requirement "update conjured items correctly". 🌹
4. Add a new feature "update conjured items correctly", following the kata's requirement. 🌹

WARNING: Beware of the goblin. Never modify the Items class!
