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.
