Detailed Description

A cell in a mesh consist of topological information (neighbours, connectivity, orientation) and geometrical information (coordinates).

This class joins the topological information from a Connector and the geometical information from an element map.

This class prescribes the common interface for all geometrical elements (cells). This interface consists of methods to query the children and the assiociated connector.
