 * Class that extends from the class L.Control.Draw and handles the back-end when a user draws on the leaflet map.

 * Since this class inherits L.Control, it is added to the AstroMap in the same way as other controls, like the zoom control.

 *

 * * @example

 *

 * ```js

 * // add a feature group to the map

 * let drawnItems = new L.FeatureGroup();

 * map.addLayer(drawnItems);

 *

 * // add draw control to map

 * let drawControl = new Draw({

 * edit: {

 *    featureGroup: drawnItems

 * },

 *    targetMap: map

 * }).addTo(map);

 * ```
