* \brief Divide an image region along the slowest dimension
*
* ImageRegionSplitterSlowDimension divides an ImageRegion into smaller regions.
* ImageRegionSplitterSlowDimension is the default splitter for many situations.
*
* This ImageRegionSplitterSlowDimension class divides a region along the
* outermost or slowest dimension. If the outermost dimension has size
* 1 (i.e. a volume with a single slice), the ImageRegionSplitter will
* divide the region along the next outermost dimension. If that
* dimension has size 1, the process continues with the next outermost
* dimension.
