Roman Numerals Kata

Done as a recorded exercise for TechReturners, following the kata at CodingDojo.

The priority here was to practice TDD, and the red-green-refactor cycle.

Notes

As the explanatory link from the CodingDojo site was not simple to parse, I chose to follow the "standard form" of Roman Numerals as defined on wikipedia:

	Thousands	Hundreds	Tens	Units
1	M	C	X	I
2	MM	CC	XX	II
3	MMM	CCC	XXX	III
4		CD	XL	IV
5		D	L	V
6		DC	LX	VI
7		DCC	LXX	VII
8		DCCC	LXXX	VIII
9		CM	XC	IX
