 \class CntViewManager
 \brief
 View manager is a class between mainwindow and different views. It is used to provide navigation between views and also creating the views for the mainwindow.
 Pointer to viewmanager is passed to each created view and therefore they can access also QMainWindow that is normally not possible. This is needed e.g. when we want to
 change or activate view from some other view.
