Support for detecting all types of geo_points

[siddharthlatest]

geo_points can be specified in the following format:

geo_point: "lat, lon"  (1)
geo_point: [lon, lat]  (2)
geo_point: {           (3)
  lat: lat,
  lon: lon
}

These values can be either passed directly to a key or as elements in an Array. GEM should support detections for all (1), (2), (3) formats in both cases.
