Converts Roman numerals to decimal value. For example, if the Roman numeral is X then the valueOf method returns 10
The valueOf method assumes the parameter is one of either: I X L C D M

Returns the integer value of the given Roman numeral (one of I X L C D M)
@param numeral a single Roman numeral (char)
@return the integer value of numeral
