Calculates the "nearness" of the two points.

Method Details
- measureNearness
  
  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
