def geocode


(or other as specified in +geocoded_by+). Returns coordinates (array).
Look up coordinates and assign to +latitude+ and +longitude+ attributes

def reverse_geocode


in +reverse_geocoded_by+). Returns address (string).
Look up address and assign to +address+ attribute (or other as specified
# 
def reverse_geocode
  do_lookup(true) do |o,rs|
    if r = rs.first
      unless r.address.nil?

def to_coordinates


even though internally they are stored in the opposite order.
This method always returns coordinates in lat,lon order,
Coordinates [lat,lon] of the object.
# 
def to_coordinates
  coords = send(self.class.geocoder_options[:coordinates])
  coords.is_a?(Array) ? coords.reverse : []
