Caves of Zircon Tutorial

This project is part of the How to Make a Roguelike tutorial. Check out the article series if you want to make the most ouf of this project.

Improvements

These are the future improvements we'll add to the tutorial based on feedback:

• Explain also (and other scoping functions) in #4 (where it is first used) instead of #6
• Explain the point of tryToFindAttribute instead of using findAttribute: we don't need the flexibility and we're using mandatory attributes
