Gilded Rose Requirements Specification
======================================

Hi and welcome to team Gilded Rose. As you know, we are a small inn with a prime location in a
prominent city ran by a friendly innkeeper named Allison. We also buy and sell only the finest goods.
Unfortunately, our goods are constantly degrading in quality as they approach their sell by date. We
have a system in place that updates our inventory for us. It was developed by a no-nonsense type named
Leeroy, who has moved on to new adventures. Your task is to add the new feature to our system so that
we can begin selling a new category of items. First an introduction to our system:

	- All items have a SellIn value which denotes the number of days we have to sell the item
	- All items have a Quality value which denotes how valuable the item is
	- At the end of each day our system lowers both values for every item
