        Calculates a bbox around this CLLocationCoordinat2D by describing a distance that is roughly analagous to
        the radius of a circle with a center at this coordinate and the radius is the distance and inscribes the circle
        to the bbox created.
 
        This tangential point method of calculating the box is described in Handbook of Mathematics By I.N. Bronshtein,
