Added uml diagram for new architecture
Finishing adding changes
Added save image, removed dbus dependency
Removed dbus dependencies from README.md
Removed interface variable
Implemented the first new architecture example: window.
By calling controller.model() (found in __init__.py) any controller
can instantiate the model object.
Window exists for m, v and c. init variables need to be config'd
Configuration of window in model singleton
Window displays with modification to controller
