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.
