CLASS --
GRegion
GRegion defines a region composed from individual sub-areas.
DESCRIPTION
While most other spatial adts such as GRect, GPolygon defines
a single bounded area, the GRegion class defines arbitrary regions
that consists of multiple simple-shaped areas such as rectangles,
points, or polygons etc.
GRegion is implemented as a set of various spatial ADT objects (
which can be of same or different types). The total area of the
region is the union of all the sub areas.
