/** \class LabeledPointSetToPointSetMetricv4
* \brief Computes the distance metric and gradient between two
* labeled point sets.
*
* This class is generic in that it takes an unlabeled point set metric,
* such as one of the following options
*
* \li \c EuclideanDistancePointSetToPointSetMetricv4 (default)
* \li \c ExpectationBasedPointSetToPointSetMetricv4
* \li \c JensenHavrdaCharvatTsallisPointSetToPointSetMetricv4
*
* where it is assumed that the point set \c PixelType associated with
* each point is a label (i.e. \c LabelType). This class is used to find
* the total metric and total derivative based on the matching between the
* separate fixed and moving labeled point sets. This class first determines
* the common label set between the fixed and moving point sets. For each
* common label, the specified unlabeled point set metric is cloned and the
* fixed and moving point subset associated with that common label is specified
* as the fixed and moving point set input. Functionality in the base class
* (\c PointSetToPointSetMetric) is used to accumulated the value and gradient.
