## 53. Roman Numerals Encoder
1795+
1796+
Create a function that takes a positive integer less than `4,000` as its input and returns a string containing the Roman numeral representation of that integer. Modern Roman numerals are written by expressing each digit separately starting with the leftmost digit and skipping any digit with a value of zero. There can't be more than 3 identical symbols in a row. More about Roman numerals: [http://en.wikipedia.org/wiki/Roman_numerals](http://en.wikipedia.org/wiki/Roman_numerals)
