List of changes proposed in this PR (pull-request)

• Removed dependencies
  • Celery
  • Flower
  • Traefik
  • Redis
  • django leaflet which depends on gis json which depends on libgdal (C++) lib
  • docker compose, recommend using conda or virtualenv instead
  • possibly more
• Merged reprohack_hub and user apps into one to simplify the project structure
• Used js-only leaflet, added custom django form widget that utilises that
• Changed geom field (gis json) into an event_coordinate field (string) that accepts lat and long in a comma separated format e.g. 10.00939,20.93003
• Navigation bar now has a solid background, so that content without the broadcam header style doesn't appear behind it.
• Static files: Restructuring of CSS and JS packages
  • Added a reprohack_hub/static/vendor folder for third party libraries
  • Main packages e.g. JQuery, Bootstrap are managed by npm, the entire package is copied to the reprohack_hub/static/vendor/node_modules folder on gulp build. This ensures that nodejs is not needed at deployment.
• Using sqlite for local dev and mysql for pythonanywhere deployment
• Replace .env config with a config/settings/secret.py & secret_default.py instead
• Updated readme on how to run the app locally and deploying on pythonanywhere, removed the .rst version.
• Added GH workflow for CI, removed travis
• Many other minor fixes.

What should a reviewer concentrate their feedback on?

• Does the app work locally?
• Are the readme instructions clear, any missing instructions?
