The central class responsible for initializing most of the values stored
in the PatientDictContainer model and defining the visual layout of the
main window of OnkoDICOM. No class has access to the attributes
belonging to this class, except for the class's ActionHandler, which is
used to trigger actions within the main window. Components of this class
(i.e. QWidget child classes such as StructureTab, DicomView, DicomTree,
etc.) should not be able to reference this class, and rather should
exist independently and only be able to communicate with the
PatientDictContainer model. If a component needs to communicate with
another component, that should be accomplished by emitting signals
within that components, and having the slots for those signals within
this class (as demonstrated by the update_views() method of this class).
If a class needs to trigger one of the actions defined in the
ActionHandler, then the instance of the ActionHandler itself can safely
be passed into the class.
