###Brief Explanation
roman_converter && resolution_rules:
All starts with the roman to decimal conversion, i made it getting the last symbol and comparing with the previous one, 
if the previous one was bigger than the present one they would be elegible to a subtraction, after this i check if this elegible subtraction would be valid.
After this we have 2 more validations, the one which do the counting i decided to try resolve it with regular expressions.
input_processor && variables:
Here i basically used regular expressions to separate the data from the input.txt an put the organized data at the Variables object.
output_processor:
When i got to create this one i started to thing about the problem and found this possible solution:
--------------------------------------------------------------------------------------------
glob is I
prok is V
pish is X
tegj is L                  
glob glob Silver is 34 Credits -> II Silver = 34
                                  2 * Silver = 34 => Silver = 17
glob prok Gold is 57800 Credits -> IV Gold = 57800
                                  4 * Gold = 57800 => Gold = 14450
pish pish Iron is 3910 Credits -> XX Iron = 3910
                                  20 * Iron = 3910 => Iron = 195.5
--------------------------------------------------------------------------------------------

This class basically implements this idea.
