/**
 * @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: '&copy; <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: '&copy; <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).
 */

 * @class L.drawLocal

 *                  }
 *              }
 *          }
 *      });
 * ```
 *
 * 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.**

 * ### Disabling a toolbar
 *
 * If you do not want a particular toolbar in your app you can turn it off by setting the toolbar to false.
 *
 * ```js
 *      var drawControl = new L.Control.Draw({
 *          draw: false,
 *          edit: {

 *      });
 * ```
 *
 * ### Disabling a toolbar item
 *
 * If you want to turn off a particular toolbar item, set it to false. The following disables drawing polygons and
 * markers. It also turns off the ability to edit layers.
 *
 * ```js
 *      var drawControl = new L.Control.Draw({
