All changes till basic model is working

[BrandonS09]

All changed leading up to a functional MVP

[BrandonS09]

Putting known issues here so that I don't forget:

1. download_images.py is currently non-functional and returning "name 'requests' not defined"
2. Im 90% sure train_model.py is implemented incorrectly
3. Verify that auto_annotate_images, scrape_similar, and search_most_dissimilar are funcitonal

[BrandonS09]

Update, most images are downloading, some errors still occurring, seems to be in search_most_dissimilar

[BrandonS09]

Update, tests currently fail to push autopep8 changes

[BrandonS09]

Forgot to add this, unit tests are bad and need to be rewritten
