/** \class ImageRegionSplitterMultidimensional
* \brief Divide a region into several pieces.
*
* ImageRegionSplitterMultidimensional divides an ImageRegion into
* smaller regions. ImageRegionSplitterMultidimensional is used by
* the StreamingImageFilter to divide a requested output region into a
* series of smaller requests of the pipeline. This object has two
* basic methods: GetNumberOfSplits() and GetSplit().
*
* GetNumberOfSplits() is used to determine how may subregions a given
* region can be divided. You call GetNumberOfSplits with an argument
* that is the number of subregions you want. If the image region can
* support that number of subregions, that number is returned.
* Otherwise, the maximum number of splits less then or equal to the
* argumen be returned. For example, if a region splitter class only divides
* a region into horizontal slabs, then the maximum number of splits
* will be the number of rows in the region.
*
* GetSplit() returns the ith of N subregions (as an ImageRegion object).
*
* ImageRegionSplitterMultidimensional class divides a region
* into hypercubes (as opposed to the slabs used by the superclass
* ImageRegionSplitter). In other words, it splits every dimension of the
* region to form ND rectangular prisms.
