this was a pretty odd design choice, true, but i am pretty sure that i deleted some of the unnecessary things in the agent class already. because as far as i can tell none of the loaded data up there in the agent class was actually necessary for that module. And I remember deleting those things. I think somethin went wrong with the version control here at some point.

however, i now did change things again and made the following necessary function a method

   
    ### this a function from here
    ### https://www.geeksforgeeks.org/program-distance-two-points-earth/
    ### for calculating the distance between points on earth
    
    def geo_distance(self, lat1, lat2, lon1, lon2):
            # The math module contains a function named
            # radians which converts from degrees to radians.
            lon1 = radians(lon1)
            lon2 = radians(lon2)
            lat1 = radians(lat1)
            lat2 = radians(lat2)
            # Haversine formula
            dlon = lon2 - lon1
            dlat = lat2 - lat1
            a = sin(dlat / 2)**2 + cos(lat1) * cos(lat2) * sin(dlon / 2)**2
            c = 2 * asin(sqrt(a))
            # Radius of earth in kilometers. Use 3956 for miles
            r = 6371
            # calculate the result
            return c * r

And also defined the necessary constants just as agent properties

       #### of variables across agent and important 
       #### for the computation of the distance metric
       self.range_income = 117075.04
       self.range_politicalregime = 8.739999999999998
        ## max distance between two points on earth =
        ## earth circumference divided by two
       self.max_distance_on_earth = 40075.017/2 ```
