    $map->add_marker('Paris, France',    html => 'Paris');
    $map->add_marker($geo_coder_result);

Returns 1 on success, 0 if the point cannot be resolved or is out of range.

### API SPECIFICATION

#### INPUT

    point : arrayref [lat, lon] | string address | object with latitude()/longitude()
    html  : string   (optional popup label)
    icon  : string   (optional icon URL)

#### OUTPUT

### MESSAGES

    |--------------------------------------|---------------------------------------------|
    | add_marker(): unknown point type     | Point is a ref type with no lat/lon methods |

### EXAMPLES

    # Coordinate array with a popup label
    $map->add_marker([51.5074, -0.1278], html => 'London');

    # String address geocoded via the injected geocoder or Nominatim

## add\_geojson

Add a GeoJSON layer to the map.

    $map->add_geojson(\%data, style => { color => '#ff0000' }, popup => 'name');

The first argument may be a hashref/arrayref (GeoJSON structure) or a JSON string.
Returns 1 on success.

### API SPECIFICATION

#### INPUT

    data  : hashref | arrayref | string (JSON)
    style : hashref   Leaflet path-style options (color, weight, fillColor, fillOpacity)
    popup : string    Feature property name whose value becomes the popup text

#### OUTPUT

    { type => integer, value => 1 }
