=================================================================
 | 
						|
 | 
						|
To load all objects in this example consult the polygons.loader utility
 | 
						|
file (note that the *.loader files are Prolog files).
 | 
						|
 | 
						|
You will need to load the objects in the roots and relations 
 | 
						|
examples (consulting the corresponding roots.loader and relations.loader 
 | 
						|
files).
 | 
						|
 | 
						|
You will also need to consult the following files in the library directory: 
 | 
						|
events.loader, types.loader, metapredicates.loader, and hierarchies.loader.
 | 
						|
 | 
						|
In this example we have several types of polygons that can be concentric.
 | 
						|
This is represented by a concentric binary relation ensuring that whenever 
 | 
						|
a polygon is moved towards a new position, all polygons likewise concentric 
 | 
						|
are moved along with them.
