/**
 \defgroup ITKOptimizersv4 Module ITKOptimizersv4 
 This module contains ITK classes that encapsulate numerical
optimizers using a new hierarchy developed for the needs of registration with
high-dimensional transforms. These optimizers will NOT work with the metrics
in Registration/Common, but rather with the new metrics in Registration/Metricsv4.
