Bandmap WIP: geocoding integrated with add form. Add form works. Before submitting the form, client side JS makes a geocode request to Google and populates hidden lat/lon fields with the result. Successfully created a model instance on the server side. Still need to update admin dashboard, admin approval, and give out badges for adding bands to the map. Once that is done, then work on displaying the map with filtering.
