/** \class Region
* \brief A region represents some portion or piece of data.
*
* Region is an abstract class that represents some portion or
* piece of a DataObject. A region is used by the pipeline when
* processing just a portion of the data, either because 1) memory
* limits dictate that the pipeline cannot fit the entire dataset
* into memory; 2) the user has requested that only a piece of the
* dataset is to be processed; or 3) parallel (multi-threaded)
* processing of the data is required.
*
* There are two types of regions in itk: a structured region that
* specifies a rectangular piece of an image (ImageRegion), and a
* unstructured region that specifies piece i of N total pieces
* (MeshRegion). Depending on the filter (its input and output
* types, and its position in the pipeline), ImageRegion or MeshRegion
* will be used to describe the region.
*
* Region is a light-weight object and not reference counted. This
* means that is behaves differently than ITK classes that are
* reference counted. For example, smart pointer access is not
* provided, and the (subclasses') constructor, destructor,
* copy constructor and operator= are all public.
