```
double measureNearness(DoubleValuedIterator pt1,
                       DoubleValuedIterator pt2)
```
    Calculates the "nearness" of the two points. The returned value should be non-negative, with smaller values indicating the points are "nearer". A value of zero indicates "identical" points.
    As long as distance ordering is preserved, it is not necessary to return a true distance. If a true distance is required, the NearnessMeasure.nearnessToDistance(double) method will be used to convert.
    
    Parameters:
    
    pt1 - one point in the measurement
    
    pt2 - the other point in the measurement
    
    Returns:
    
    the "nearness" of the points
