GoLocal Milestone Two

This release focuses on the project backend and getting models/routes created

Database models were created for Users, Companies, Reviews, and Posts. These models were created with flask_sqlalchemy inside of an sqlite database.
API routes were created for these different database models. The routes created for the different database models include /list/, /create/, /update/, and /delete/.
Test files were created for all of these routes and models. They test any possible thing that we think could go wrong with the routes including missing fields for example.

This release gets most of our backend complete. With all of the database models created and the routes for each of them, we now have a built out API that we can use in the frontend for Milestone Three.
Using GitHub Actions, testing is now automated. Whenever a pull request is opened, the tests will automatically be ran and notify the creator of the pull request if they fail.
Restrictions were put on the main branch to make it more secure and make sure that unwanted pushes to the main branch do not occur.
