Implementation of a Roman Numeral Calculator. Depends on the the Check unit testing framework.

 $> make
 $> make test 

A Dockerfile has been included to facilitate running the appplication.

 $> cd docker
 $> docker build -t ubuntu-apparatus .
 $> docker run -it ubuntu-apparatus /bin/bash
 $> cd /tmp

For addition:

$> ./apparatus XI IX
   SVMMA: XX

One can add more than one number together.

$> ./apparatus VI IX LX
   SVMMA: LXXV

For subtraction:

$> ./apparatus -s XI IX
       SVMMA: II

One can subtract more than one number from the initial number.

$> ./apparatus -s XXX I IV X
       SVMMA: XV

The apparatus supports Alternative forms of Roman Numerals as described in Wikipedia:

The “standard” forms described above reflect typical modern usage rather than a universally
accepted convention. Usage in ancient Rome varied greatly and remained inconsistent in
medieval and modern times.

Roman inscriptions, especially in official contexts, seem to show a preference for additive
forms such as IIII and VIIII instead of (or even as well as) subtractive forms such as IV and
IX. Both methods appear in documents from the Roman era, even within the same document.
“Double subtractives” also occur, such as XIIX or even IIXX instead of XVIII. Sometimes V and
L are not used, with instances such as IIIIII and XXXXXX rather than VI or LX.
