Load/Save user data to DB (SPIN)

[danton267]

Replace the current system - saving/reading JSON-like metadata to/from local .txt file, too pushing/reading the JSON metadata to the database.

The metadata JSON already contains everything necessary - user name, project, time, and all project metadata.

Create a read query that filters by user, project, and orders by time.

• we also talked about logging any user interaction with the graph (just a timestamp, which will require a different table to log into) - what all events does this include?

1. creating annotations
2. moving/zooming
3. selecting a new image
4. interacting with any controls

Blocker

Waiting for the DB server credentials and a sample read/write usage.
