Learning exercise, writing a code kata to convert numbers to roman numerals. Find a detailed description of the kata at: https://codingdojo.org/kata/RomanNumerals/

The Romans wrote numbers using letters : I, V, X, L, C, D, M. (notice these letters have lots of straight lines and are hence easy to hack into stone tablets) Part I

The Kata says you should write a function to convert from normal numbers to Roman Numerals: eg

 1 --> I
 3 --> III
 4 --> IV
 5 --> V
 6 --> VI
 7 --> VII
 8 --> VIII
 9 --> IX
 10 --> X
 30 --> XXX
 40 --> XL
 50 --> L
 100 --> C
 300 --> CCC
 400 --> CD
 500 --> D
 900 --> CM
 1000 --> M
 1300 --> MCCC
 1500 --> MD
 1832 --> MDCCCXXXII
etc.

For a full description of how it works, take a look at this useful reference website.

There is no need to be able to convert numbers larger than about 3000. (The Romans themselves didn’t tend to go any higher.)
