Improves behavior when signs share conditions
Makes sure that the paid sign matching the most conditions is always chosen as the matching paid sign Makes sure to always choose the most expensive paid sign if two or more paid signs with the same amount of conditions are matching. Changes some classes to records to reduce some boilerplate code
