Detailed Description

Defines the class TdkView.

This class a crucial component in the tdk architecture. It is responsible for representing a map and controlling all the communication between components that are associated with one map (legend, map display, data view_ and graph dialog), for that reason it keeps pointers to all these classes. Every time one component modifies the map somehow, the other components must be warned and this is acomplished by the TdkView class.
