Using dataclass to pass around contextual classes properly.
Refactored the import features to make use of the dataclass.
Adding in-line file handling support (included images)

TODO: If the model used doesn't support images... well I am not
      sure what happens. But also, I know certain models want a
      specific format (or perhaps I should say API). So we might
      be okay.
