I got tired of APRS-IS websites not showing me all the paths that packets
take, only the shortest path to IS. So this is a Python 3 tool that turns
direwolf logs into a REST API in JSON format.

## Setup
1. Run direwolf with logging to CSV on by using `-l`. (`-L` not yet implemented).
1. Install requirements using `pip install -r requirements.txt`.
1. Set up database file with `python init_db.py`.
2. Run `app.py` with either a Python call or a real WSGI server.
You can use screen to detach the session.
    - Default URL is http://127.0.0.1:5000
    - Example `waitress` and `screen` scripts are included, see
      - `api_waitress.py` and
      - `start-aprs_api.sh`
3. Access the API from whatever other system you want.

## Endpoints:
-`/packets` - gives the most recent packets, sorted descending by time received.
    - argument `n` will return a specific number of packets, default 10. E.g.,
    `https://digi.w1cdn.net/aprs_api/packets?n=1` returns one packet.

Example of an object packet sent by W1CDN-1 and digipeated by K0UND-2:
