/**
 * @classdesc
 * The map is the core component of OpenLayers. For a map to render, a view,
 * one or more layers, and a target container are needed:
 *
 *     var map = new ol.CanvasMap({
 *       view: new ol.View({
 *         center: [0, 0],
 *         zoom: 1
 *       }),
 *       layers: [
 *         new ol.layer.Tile({
 *           source: new ol.source.OSM()
 *         })
 *       ],
 *       target: 'map'
 *     });
 *
 * The above snippet creates a map using a {@link ol.layer.Tile} to display
 * {@link ol.source.OSM} OSM data and render it to a DOM element with the
 * id `map`.
 *
 * The constructor places a viewport container (with CSS class name
 * `ol-viewport`) in the target element (see `getViewport()`), and then two
 * further elements within the viewport: one with CSS class name
 * `ol-overlaycontainer-stopevent` for controls and some overlays, and one with
 * CSS class name `ol-overlaycontainer` for other overlays (see the `stopEvent`
 * option of {@link ol.Overlay} for the difference). The map itself is placed in
 * a further element within the viewport.
 *
 * Layers are stored as a `ol.Collection` in layerGroups. A top-level group is
 * provided by the library. This is what is accessed by `getLayerGroup` and
 * `setLayerGroup`. Layers entered in the options are added to this group, and
 * `addLayer` and `removeLayer` change the layer collection in the group.
 * `getLayers` is a convenience function for `getLayerGroup().getLayers()`.
 * Note that `ol.layer.Group` is a subclass of `ol.layer.Base`, so layers
 * entered in the options or added with `addLayer` can be groups, which can
 * contain further groups, and so on.
