Roman Numeral Calculator Kata

A library which allows the addition and subtraction of Roman numerals.

Requires the Check unit testing framework.

Run make to build and run the tests.

You can also run make clean to remove build artifacts or make build/libroman_calculator.a to just build the library.

Some considerations

• The romans had no way of representing negative numbers, however I felt it would be more useful for the library to handle this by appending a - than to give some sort of error.
• In the int_to_char function, there is an assert. This is there to guard against potential changes to base_values and glyphs so that they are guaranteed to have the same number of elements. I could not think of an external way to test this.
