Created Controller Class, Model Class, and refactored the interface slightly

[kiraoyd]

Broke interface into two seperate interfaces (toFile and fromFile). Wrote the JsonModel class (still in interfaceDatabase.py, we can change up class-file placement later) which implements BOTH interfaces), updated the Controller class, removed dependencies between the Controller and Model, updates some of the main calling routing (just a brainstorm really, not final in any way) that lives in Controller.py (location can change)

Dont we want the meat and potatoes of databaseInterface.py? i.e. or are we just keeping everything abstract?

[kiraoyd]

The meat and potatoes still exists, it's just being moved into the Model class implementation
