/**
* \class PolygonGroupSpatialObject
* \brief Implements a Region Of Interest Type
*
* This class implements a Region of Interest, which is simply a space
* in a medical image that has some significance as a component of the
* scan. Different components of brain anatomy, for instance are Regions
* of Interest in the human brain.
* The primary difference between PolygonGroupSpatialObject and other
* descendants of SpatialObject are these:
* 1. For now, an PolygonGroup needs to comprise a series of slices parallel to
* a plane swept by any two of the major axes. In other words, the points
* in each slice (or strand) all need to have one of the X,Y,Z values to
* be constant.
* 2. The IsInside method implements the concept of spatial 'insidedness'
* where other descendents of SpatialObject have a concept of insidedness
* defined in a rather ad-hoc manner. PolygonGroupSpatialObjects define IsInside
* to mean that the given point resides in space inside the surface of
* the PolygonGroupSpatialObject.
