Description:

This package supports both conventional Roman algarisms (which range from 1 to
3999) and Milhar Romans, a variation which uses a bar across the algarism to
indicate multiplication by 1,000. For the purposes of this module, acceptable
syntax consists of an underscore suffixed to the algarism e.g. IV_V = 4,005.
The term Milhar apparently derives from the Portuguese word for "thousands" and
the range of this notation extends the range of Roman numbers to 3999 x 1000 +
3999 = 4,002,999.

Note: the functions in this package treat Roman algarisms in a case-insensitive
manner such that "VI" == "vI" == "Vi" == "vi".
