/**
* @class L.Draw
* @aka Draw
*
*
* To add the draw toolbar set the option drawControl: true in the map options.
*
* @example
* ```js
* var map = L.map('map', {drawControl: true}).setView([51.505, -0.09], 13);
*
* L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
* attribution: '© <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
* }).addTo(map);
* ```
*
* ### Adding the edit toolbar
* To use the edit toolbar you must initialise the Leaflet.draw control and manually add it to the map.
*
* ```js
* var map = L.map('map').setView([51.505, -0.09], 13);
*
* L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
* attribution: '© <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
* }).addTo(map);
*
* // FeatureGroup is to store editable layers
* var drawnItems = new L.FeatureGroup();
* map.addLayer(drawnItems);
*
* var drawControl = new L.Control.Draw({
* edit: {
* featureGroup: drawnItems
* }
* });
* map.addControl(drawControl);
* ```
*
* The key here is the featureGroup option. This tells the plugin which FeatureGroup contains the layers that
* should be editable. The featureGroup can contain 0 or more features with geometry types Point, LineString, and Polygon.
* Leaflet.draw does not work with multigeometry features such as MultiPoint, MultiLineString, MultiPolygon,
* or GeometryCollection. If you need to add multigeometry features to the draw plugin, convert them to a
* FeatureCollection of non-multigeometries (Points, LineStrings, or Polygons).
*/

* polygon: 'Draw an awesome polygon'
* }
* }
* }
* });
* ```
*
* The default state for the control is the draw toolbar just below the zoom control.
* This will allow map users to draw vectors and markers.
* **Please note the edit toolbar is not enabled by default.**
