This project is based on the following exercise:

Roman Numeral Calculator

For this programming exercise, you will be creating a library which will allow the addition and subtraction of Roman numerals. Once your solution is complete, please provide your solution as a Git repository (publicly available via Github or Bitbucket). Please include within your repository, all source and test code.

This exercise is based on the Roman Numeral Calculator Kata at http://bit.ly/1VfHqlj.

Please submit your test driven solution via a public Git repository (github/bitbucket).

The solution will be reviewed for:

• Test coverage
• Test Driven Development
• Algorithm Usage
• Code structure
• Use of source control
• Completeness of the overall solution

The environment for this programming exercise must utilize:

• Ubuntu Linux 14.04
• The C programming language
• GNU GCC compiler tool chain
• GNU Make
• Check unit testing framework ( https://libcheck.github.io/check/ )
• git

Roman Numeral rules:

• Roman numerals consist of the following letters: I, V, X, L, C, D, and M which mean one, five, ten, fifty, hundred, five hundred and one thousand respectively.
• An example would be "XIV" + "LX" = "LXXIV" 

• Numerals can be concatenated to form a larger numeral ("XX" + "II" = "XXII").
• If a lesser numeral is put before a bigger it means subtraction of the lesser from the bigger ("IV" 
means four, "CM" means ninehundred).
• If the numeral is I, X or C you can't have more than three ("II" + "II" = "IV" not “IIII”).
• If the numeral is V, L or D you can't have more than one ("D" + "D" = "M" not “DD”)
• The maximum roman numeral is 3999 (MMMCMXCIX)

User Story: Addition

As a Roman bookkeeper, I want to be able to add two numbers together; so that I can do my work faster with fewer mathematical errors. 


User Story: Subtraction

As a Roman bookkeeper, I want to be able to subtract one number from another; so that I can do my work faster and with fewer mathematical errors.
