+/**
+ * Description:
+ * Create a function taking a positive integer as its parameter and returning a string containing the Roman Numeral
+ * representation of that integer.
+ * Modern Roman numerals are written by expressing each digit separately starting with the left most digit and skipping
+ * any digit with a value of zero. In Roman numerals 1990 is rendered: 1000=M, 900=CM, 90=XC; resulting in MCMXC.
+ * 2008 is written as 2000=MM, 8=VIII; or MMVIII. 1666 uses each Roman symbol in descending order: MDCLXVI.
+ * Example:
+ * conversion.solution(1000); //should return "M"
