About this Kata

A refactoring Kata, bases on existing code.

Problem Description

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:

The Martin Fowler’s book “Refactoring, Improving the Design of Existing Code” start with a (very) simple example of refactoring of code.

Actualy the statement method prints out a simple text output of a rental statement

Rental Record for martin
  Ran 3.5
  Trois Couleurs: Bleu 2
Amount owed is 5.5
You earned 2 frequent renter points

We want to write an HTML version of the statement method :

<h1>Rental Record for <em>martin</em></h1>
<table>
  <tr><td>Ran</td><td>3.5</td></tr>
  <tr><td>Trois Couleurs: Bleu</td><td>2</td></tr>
</table>
<p>Amount owed is <em>5.5</em></p>
<p>You earned <em>2</em> frequent renter points</p>

First refactor the program to make it easy to add the feature, then add the feature.
