/**
* @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:
*
* import Map from 'ol/Map.js';
* import View from 'ol/View.js';
* import TileLayer from 'ol/layer/Tile.js';
* import OSM from 'ol/source/OSM.js';
*
* const map = new Map({
* view: new View({
* center: [0, 0],
* zoom: 1,
* }),
* layers: [
* new TileLayer({
* source: new OSM(),
* }),
* ],
* target: 'map',
* });
*
* The above snippet creates a map using a {@link module:ol/layer/Tile~TileLayer} to
* display {@link module:ol/source/OSM~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 module:ol/Overlay~Overlay} for the difference). The map
* itself is placed in a further element within the viewport.
*
* Layers are stored as a {@link module:ol/Collection~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 {@link module:ol/layer/Group~LayerGroup}
* is a subclass of {@link module:ol/layer/Base~BaseLayer}, so layers entered in the
* options or added with `addLayer` can be groups, which can contain further
* groups, and so on.
