   * @example
   *
   * ```js
   * map.on('click', function(e) {

   *
   * Leaflet deals with event listeners by reference, so if you want to add a listener and then remove it, define it as a function:
   *
   * ```js
   * function onClick(e) { ... }
   *
   * map.on('click', onClick);
   * map.off('click', onClick);

   *

   *
   * ```js

   *
   * The `baseLayers` and `overlays` parameters are object literals with layer names as keys and `Layer` objects as values:
   *
   * ```js
   * {
   *     "<someName1>": layer1,
   *     "<someName2>": layer2
   * }
   * ```
   *
   * The layer names can contain HTML, which allows you to add additional styling to the items:
   *
   * ```js
   * {"<img src='my-layer-icon' /> <span class='my-layer-item'>My Layer</span>": myLayer}

   * @class Polygon
   * @aka L.Polygon
   * @inherits Polyline
   *
   * A class for drawing polygon overlays on a map. Extends `Polyline`.
   *
   * Note that points you pass when creating a polygon shouldn't have an additional last point equal to the first one — it's better to filter out such points.
   *
   *
   * @example
   *
   * ```js
   * // create a red polygon from an array of LatLng points
   * var latlngs = [[37, -109.05],[41, -109.03],[41, -102.05],[37, -102.04]];
   *
   * var polygon = L.polygon(latlngs, {color: 'red'}).addTo(map);
   *
   * // zoom the map to the polygon
   * map.fitBounds(polygon.getBounds());
   * ```
   *
   * You can also pass an array of arrays of latlngs, with the first array representing the outer shape and the other arrays representing holes in the outer shape:
   *
   * ```js
   * var latlngs = [
   *   [[37, -109.05],[41, -109.03],[41, -102.05],[37, -102.04]], // outer ring
   *   [[37.29, -108.58],[40.71, -108.58],[40.71, -102.50],[37.29, -102.50]] // hole
   * ];
   * ```
   *
   * Additionally, you can pass a multi-dimensional array to represent a MultiPolygon shape.
   *
   * ```js
   * var latlngs = [
   *   [ // first polygon
   *     [[37, -109.05],[41, -109.03],[41, -102.05],[37, -102.04]], // outer ring
   *     [[37.29, -108.58],[40.71, -108.58],[40.71, -102.50],[37.29, -102.50]] // hole
   *   ],
   *   [ // second polygon
   *     [[41, -111.03],[45, -111.04],[45, -104.05],[41, -104.05]]
   *   ]

   * @class GridLayer
   * @inherits Layer
   * @aka L.GridLayer
   *
   * Generic class for handling a tiled grid of HTML elements. This is the base class for all tile layers and replaces `TileLayer.Canvas`.
   * GridLayer can be extended to create a tiled grid of HTML elements like `<canvas>`, `<img>` or `<div>`. GridLayer will handle creating and animating these DOM elements for you.
   *
   *
   * @section Synchronous usage
   * @example
   *
   * To create a custom layer, extend GridLayer and implement the `createTile()` method, which will be passed a `Point` object with the `x`, `y`, and `z` (zoom level) coordinates to draw your tile.
   *
   * ```js
   * var CanvasLayer = L.GridLayer.extend({
   *     createTile: function(coords){
   *         // create a <canvas> element for drawing
   *         var tile = L.DomUtil.create('canvas', 'leaflet-tile');
   *
   *         // setup tile width and height according to the options
   *         var size = this.getTileSize();
   *         tile.width = size.x;
   *         tile.height = size.y;
   *
   *         // get a canvas context and draw something on it using coords.x, coords.y and coords.z
   *         var ctx = tile.getContext('2d');
   *
   *         // return the tile so it can be rendered on screen
   *         return tile;
   *     }
   * });
   * ```
   *
   * @section Asynchronous usage
   * @example
   *
   * Tile creation can also be asynchronous, this is useful when using a third-party drawing library. Once the tile is finished drawing it can be passed to the `done()` callback.
   *
   * ```js
   * var CanvasLayer = L.GridLayer.extend({
   *     createTile: function(coords, done){
   *         var error;
   *
   *         // create a <canvas> element for drawing
   *         var tile = L.DomUtil.create('canvas', 'leaflet-tile');
   *
   *         // setup tile width and height according to the options
   *         var size = this.getTileSize();
   *         tile.width = size.x;
   *         tile.height = size.y;
   *
   *         // draw something asynchronously and pass the tile to the done() callback
   *         setTimeout(function() {
   *             done(error, tile);
   *         }, 1000);
   *
   *         return tile;
   *     }
   * });
   * ```

/**
  # wildcard

  Very simple wildcard matching, which is designed to provide the same
  functionality that is found in the
  [eve](https://github.com/adobe-webplatform/eve) eventing library.

  ## Usage

  It works with strings:

  <<< examples/strings.js

  Arrays:

  <<< examples/arrays.js

  Objects (matching against keys):

  <<< examples/objects.js

  ## Alternative Implementations

  - <https://github.com/isaacs/node-glob>

    Great for full file-based wildcard matching.

  - <https://github.com/sindresorhus/matcher>

     A well cared for and loved JS wildcard matcher.

 * Ideally I would have loved to have a single MapPreviewPopup object and recycle it throughout the app's
 * lifetime. But I was unable to get this to work smoothly due to annoying flashes of the old map when moving
 * between links. Everything I tried, e.g. showing the popup only when the map's 'moveend' event was fired,
 * led to more problems.
 * So the way it works for now, is that a MapPreviewPopup shows a single map, and the map is recreated
 * every time the user hovers a link, requiring loading all the markers etc.
