Initial DB tables
Register / "login". Currently this redirects to "gym.local:8000", so I suppose just change that part of the url to the hostname you used.
Implement `GET /user` and `GET /user/friends`.
Implement `PUT user`. (not thoroughly tested due to slow internet x_x)
Implement "pay", transactions, and goal.
