14///One tab in the Notebook that is placed in the main window (\ref MainWin).
15
16///One graph and all of its accessories like maps are assigned to one tab in the notebook.
17///\ref NoteBookTab is responsible for the user defined display of the graph: view can be
18///set by visualized maps, therefore \ref NoteBookTab must provide an interface to set the
19///view of graph. This is \ref Mapwin window.
20///
21///\ref NoteBookTab is also
22///responsible for modify the graph if it is
23///requested. Therefore it is responsible for translating user events to modifications to
24///do on graph, like node/edge addition/deletion, map modification, addition and so on.
25///
26///To be able to solve these tasks the help of \ref MainWin is also needed, for example to
27///know which editor-tool is active at the moment. Therefore \ref MainWin knows \ref NoteBookTab.
28///
29///Some information in the other direction is needed as well: for example when new map creation is requested for this tab
30///\ref NoteBookTab must ask \ref MainWin to pop-up a \ref NewMapWin. Communication in this direction is realized by signals
31///therefore \ref NoteBookTab does not know \ref MainWin at all, but in this way it is not necessary.
