I have a CoreData entity X, and controllers for this entity, XController. Now there's another entity, XGroup, containing a collection of X entities, and a XGroupController.

Each cartographic point stores: A] geographic and spatial coordinates, cartographic distortions, etc. B] pointer to north/south/east/west node. It allows to store relationships between points, first of all their affiliation to the meridian/parallel... class...
