Title: Shujing

Added evaluation of how far a current state has achieved a goal, compared to its original state value.
Allowed the goal, current and original states have different state type (EQUAL_TO, GREAT_THAN, FUZZY_WITHIN,and so on), and different value type (int, float, bool, Entity, Vector, fuzzy_value and so on)
