Support longitude and latitude format for geo coordinates

[ppf2]

K4_b2. A lot of the datasets out there use longitude and latitude format for geo coordinates. It looks like the new map component supports only geohash coordinates. Would be nice to provide support for one of the geo point types that use long and lat (http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-geo-point-type.html#_input_structure) as well.

Hmm never mind it looks like my geojson array ("geocode":[-117.7339,33.675099999999986]) is mapped as a double instead a geo_point. That is probably why it is not showing up as an option in the map.
