class TStructViewer: public TObject

 TStructViewer viewer represents class, struct or other type as an object in 3D space.
 At the top of the scene we can see objects which is our pointer. Under it we see
 pointers and collection elements. Collection must inherit from TCollection
 or be STL collecion.

 We can change the number of visible levels or objects on the scene with the  GUI or
 methods. The size of geometry objects is proportional to the memory taken by this object
 or to the number of members inside this object.

 An easy way to find some class in the viewer is to change the color of the type.
 We can connect for example a TF2 class with red color or connect all classes
 inheriting from TF2 by adding plus to name. For example typename "TF2+" tells us
 that all classes inheriting from TF2 will be red.

 Navigation in viewer is very simple like in usual GLViewer. When you put the mouse over
 some object you can see some information about it (e.g. name, size, actual level).
 When you double click this object, it becames top object on scene.
 Undo and redo operation are supported.

In this picture we can see TStructViewer with pointer to TList which contains other collections and objects of various classes
