code: public static NearbySearchRequest nearbySearchNextPage(
        GeoApiContext context, String nextPageToken) {
      NearbySearchRequest request = new NearbySearchRequest(context);
      request.pageToken(nextPageToken);
      return request;
    }
docs: Retrieves the next page of Nearby Search results. The nextPageToken, returned in a
  PlacesSearchResponse when there are more pages of results, encodes all of the original Nearby
  Search Request parameters, which are thus not required on this call.
  
  @param context The context on which to make Geo API requests.
  @param nextPageToken The nextPageToken returned as part of a PlacesSearchResponse.
  @return Returns a NearbySearchRequest that can be executed.
