We have the Nominatim and the Google Geocoder Service.
By default Google is used, and as a fallback the Nominatim Geocoder.
Google no longer offers a public access to their API.
An apiKey is required.
The same is true for the Nominatim Geocoder.
Originally we used the Open Mapquest Geocoder, which was called Nominatim.
However, they also do not provide free/public access anymore.
An apiKey is also required.
The current code can no longer be used and must be reworked to support MapQuest and Google's new way of things.
