25 - A GroupScene is composed of a single GroupItem that contains BlockItem and ConnectionItem
26 The GroupItem is stored in the mainGroup attribute
28 - A GroupScene is instanciated whenever there is a GroupItem that must be created, i.e.
29 for the top scene or for subgroups.
31 - This class is a subclass of QGraphicsScene by convenience but it's goal is more to list
32 the different inner items. Thus, all operations that add/remove items to the scene will also

42 - AddConnection: can only add connections to the scene
43 - AddGroup: while a new group (empty or from selected blocks) is created
44 - ItemEdtion: can move/resize blocks/interfaces, remove blocks/interface/group, ...
