Create a function taking a non-negative integer as its parameter and returning a string containing the Roman Numeral representation of that integer.
By convention, "modern" Roman numerals are written by expressing each digit separately starting with the leftmost digit and skipping any digit with a value of zero.
Examples
- If n is 1990 then romStr = 'MCMXC' since 1000=M, 900=CM, 90=XC.
- If n is 2008 then romStr = 'MMVIII' since 2000=MM, 8=VIII.
- If n is 1666 then romStr = 'MDCLXVI'.
- If n is 0 then romStr is empty ([] and '' are both acceptable)
n will always be an integer between 0 and 3999 (inclusive).

It would be good if Cody penalized huge strings. :)

Solution uses regexprep with dynamic operators for the replacement expression which outsmarts Cody's size calculation.

This is just silly. It's gaming the Matlab grader, and not doing a particularly good job at that. Why should this stop at 3999?
