 *
 * \brief Version of the pattern intensity metric for registrations with multiple fixed images.
 *
 * This class implements the Pattern Intensity metric for registrations with
 * multiple fixed images. The class includes the SetRadius and SetSigma
 * methods, which sets the Radius and Sigma parameters on each of the
 * individual metrics contained within the class (please see the
 * PatternIntensityImageToImageMetric class for a brief description of these
 * parameters).
