def self.call_geocoder_service(url)
  Timeout::timeout(Geokit::Geocoders::request_timeout) { return self.do_get(url) } if Geokit::Geocoders::request_timeout
  self.do_get(url)
rescue TimeoutError
  nil
end

.do_reverse_geocode(latlng) ⇒ Object

Not all geocoders can do reverse geocoding. So, unless the subclass explicitly overrides this method, a call to reverse_geocode will return an empty GeoLoc. If you happen to be using MultiGeocoder, this will cause it to failover to the next geocoder, which will hopefully be one which supports reverse geocoding.

  GeoLoc.new
end

.geocode(address, *args) ⇒ Object

Main method which calls the do_geocode template method which subclasses are responsible for implementing. Returns a populated GeoLoc or an empty one with a failed success code.
