outFIT Hack Challenge Final Submission
Group no: 14

Backend using SQL Alchemy creates 3 tables called users, outfits, and clothes. 
Implements 17 routes across 3 tables, including dealing with images in the tops and bottoms routes. 

Synchronized upload of images to both AWS S3 Bucket and SQL database hosted on Heroku
Heroku API link: https://outfithackchallenge.herokuapp.com/api/bottoms/

Please note that uploading images to heroku only works with png and jpeg images only, once they have been converted to base 64.
We use https://www.base64-image.de/ as our image converter, then copy paste the text into our POST request body with the "image_name" key

If this is not December 2021 the heroku and AWS accounts may be deactivated to save costs since this is for a school side project.
