GeoLocation

Adding GeoLocation attribute to a model enables Geo queries through _query parameter inside a GET request.

data class Poi(val name: String,
               val description: String,
               val location: GeoLocation)

This will add a GeoLocation attribute to API requests.
The body will be made like that

{
   "name":"McDonald's",
   "description":"McDonald's in this place is very useful and good for drivers",
   "location": {
      "type":"Point",
      "coordinates":[35.5752569,10.2168173]
   }
}

A query that retrieves documents near a specific location is made like this

pois?_query={"location":{"$near":{"$geometry":{"type":"Point","coordinates":[35.530878,10.2354807]}, "$maxDistance": 500}}}
