A Brand New Approach to the Gilded Rose Kata

Today, I have completed the Gilded Rose Kata for the third and final time. Below are my notes:

• Instead of focusing on TDD, I decided to use a test suite from my previous attempt at the kata.
• I refactored the updateQuality() method to simply iterate through the item list apply rules to the items, if there are any.
• The rules have been changed to be stored in a HashMap. Whenever I wanted to apply rules to an item, I could simply access the item's list of rules by using the item's name as a key.
• Each rule consists of a sellIn point, a qualityChange amount, and a sellInChange amount.
• I decided that no rule would cancel out another rule, unless it is explicitly told to do so.
• Refactoring the updateQuality() method while having the test cases in place was fun!

P.S. I would have to say that my level of self-awareness of copying code is II. Please see what the levels mean in my learning plan.
