/** \class ReflectiveImageRegionIterator
* \brief Multi-dimensional image iterator which only walks a region.
*
* ReflectiveImageRegionIterator is a templated class to represent a multi-dimensional
* iterator. ReflectiveImageRegionIterator is templated over the image type
* ReflectiveImageRegionIterator is constrained to walk only within the
* specified region and along a line parallel to one of the coordinate axis.
*
* Most of the functionality is inherited from the ReflectiveImageRegionConstIterator.
* The current class only adds write access to image pixels.
