Provide convenient fine-tuning tool for users

[daniel-j-h]

We should provide a tool where the user can load up a pre-trained model, point it at a dataset (e.g. directory of labeled videos), and have it fine-tune the model automatically.

you can easily repurpose the reference script from torchvision for that :)
