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

// 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.

// 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

// Pretty simple, right? Well this is where it gets interesting:

// 	- The Quality of an item is never negative
// 	- "Aged Brie" actually increases in Quality the older it gets
// 	- The Quality of an item is never more than 50
// 	- "Sulfuras", being a legendary item, never has to be sold or decreases in Quality
// 	- "Backstage passes", like aged brie, increases in Quality as its SellIn value approaches;

// Just for clarification, an item can never have its Quality increase above 50, however "Sulfuras" is a
// legendary item and as such its Quality is 80 and it never alters.
