 - At the end of each day our system lowers both values for every item
 
 # unit tests
--[x] At the end of each day our system lowers both values for every item
--[x] Once the sell by date has passed, Quality degrades twice as fast
--[x] The Quality of an item is never negative
--[x] "Aged Brie" actually increases in Quality the older it gets
--[x] The Quality of an item is never more than 50
--[x] "Sulfuras", being a legendary item, never has to be sold or decreases in Quality
--[x] "Backstage passes", like aged brie, increases in Quality as its SellIn value approaches;
-    -[x] Quality increases by 2 when there are 10 days or less and by 3 when there are 5 days or less but
-    -[x] Quality drops to 0 after the concert
--[x] an item can never have its Quality increase above 50
-    -[x] however "Sulfuras" is a legendary item and as such its Quality is 80 and it never alters.

 ## Technical Issues, with a balanced priority
--[x] item names are hardcoded
--[x] items are identified by the name in a hardcoded way
--[x] nested logic
--[x] long method

 ## Refactoring actions
--[x] extract hardcoded variables
--[x] create polymorphism for items
--[x] move item names as item members
--[x] extract methods
--[x] extract boolean methods
--[x] encapsulate methods
