+ * This extends {@link ol.Observable} with observable properties, where each
+ * property is observable as well as the object as a whole.
+ *
+ * Classes that inherit from this have pre-defined properties, to which you can
+ * add your owns. The pre-defined properties are listed in this documentation as
+ * 'Observable Properties', and have their own accessors; for example,
+ * {@link ol.Map} has a `target` property, accessed with `getTarget()` and
+ * changed with `setTarget()`. Not all properties are however settable. There
+ * are also general-purpose accessors `get()` and `set()`. For example,
+ * `get('target')` is equivalent to `getTarget()`.
+ *
+ * The `set` accessors trigger a change event, and you can monitor this by
+ * registering a listener. For example, {@link ol.View} has a `center`
+ * property, so `view.on('change:center', function(evt) {...});` would call the
+ * function whenever the value of the center property changes. Within the
+ * function, `evt.target` would be the view, so `evt.target.getCenter()` would
+ * return the new center.
+ *
+ * You can add your own observable properties with
+ * `object.set('prop', 'value')`, and retrieve that with `object.get('prop')`.
+ * You can listen for changes on that property value with
+ * `object.on('change:prop', listener)`. You can get a list of all
+ * properties with {@link ol.Object#getProperties object.getProperties()}.
+ *
+ * Note that the observable properties are separate from standard JS properties.
+ * You can, for example, give your map object a title with
+ * `map.title='New title'` and with `map.set('title', 'Another title')`. The
+ * first will be a `hasOwnProperty`; the second will appear in
+ * `getProperties()`. Only the second is observable.
+ *
+ * Properties can be deleted by using the unset method. E.g.
+ * object.unset('foo').

+/**
+ * @classdesc
+ * An ol.View object represents a simple 2D view of the map.
+ *
+ * This is the object to act upon to change the center, resolution,
+ * and rotation of the map.
+ *
+ * ### The view states
+ *
+ * An `ol.View` is determined by three states: `center`, `resolution`,
+ * and `rotation`. Each state has a corresponding getter and setter, e.g.
+ * `getCenter` and `setCenter` for the `center` state.
+ *
+ * An `ol.View` has a `projection`. The projection determines the
+ * coordinate system of the center, and its units determine the units of the
+ * resolution (projection units per pixel). The default projection is
+ * Spherical Mercator (EPSG:3857).
+ *
+ * ### The constraints
+ *
+ * `setCenter`, `setResolution` and `setRotation` can be used to change the
+ * states of the view. Any value can be passed to the setters. And the value
+ * that is passed to a setter will effectively be the value set in the view,
+ * and returned by the corresponding getter.
+ *
+ * But an `ol.View` object also has a *resolution constraint*, a
+ * *rotation constraint* and a *center constraint*.
+ *
+ * As said above, no constraints are applied when the setters are used to set
+ * new states for the view. Applying constraints is done explicitly through
+ * the use of the `constrain*` functions (`constrainResolution` and
+ * `constrainRotation` and `constrainCenter`).
+ *
+ * The main users of the constraints are the interactions and the
+ * controls. For example, double-clicking on the map changes the view to
+ * the "next" resolution. And releasing the fingers after pinch-zooming
+ * snaps to the closest resolution (with an animation).
+ *
+ * The *resolution constraint* snaps to specific resolutions. It is
+ * determined by the following options: `resolutions`, `maxResolution`,
+ * `maxZoom`, and `zoomFactor`. If `resolutions` is set, the other three
+ * options are ignored. See documentation for each option for more
+ * information.
+ *
+ * The *rotation constraint* snaps to specific angles. It is determined
+ * by the following options: `enableRotation` and `constrainRotation`.
+ * By default the rotation value is snapped to zero when approaching the
+ * horizontal.
+ *
+ * The *center constraint* is determined by the `extent` option. By
+ * default the center is not constrained at all.

+ * @extends {ol.Object}

+ * @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.
+ *

+ * @classdesc
+ * The ol.DeviceOrientation class provides access to information from
+ * DeviceOrientation events. See the [HTML 5 DeviceOrientation Specification](
+ * http://www.w3.org/TR/orientation-event/) for more details.
+ *
+ * Many new computers, and especially mobile phones
+ * and tablets, provide hardware support for device orientation. Web
+ * developers targeting mobile devices will be especially interested in this
+ * class.
+ *
+ * Device orientation data are relative to a common starting point. For mobile
+ * devices, the starting point is to lay your phone face up on a table with the
+ * top of the phone pointing north. This represents the zero state. All
+ * angles are then relative to this state. For computers, it is the same except
+ * the screen is open at 90 degrees.
+ *
+ * Device orientation is reported as three angles - `alpha`, `beta`, and
+ * `gamma` - relative to the starting position along the three planar axes X, Y
+ * and Z. The X axis runs from the left edge to the right edge through the
+ * middle of the device. Similarly, the Y axis runs from the bottom to the top
+ * of the device through the middle. The Z axis runs from the back to the front
+ * through the middle. In the starting position, the X axis points to the
+ * right, the Y axis points away from you and the Z axis points straight up
+ * from the device lying flat.
+ *
+ * The three angles representing the device orientation are relative to the
+ * three axes. `alpha` indicates how much the device has been rotated around the
+ * Z axis, which is commonly interpreted as the compass heading (see note
+ * below). `beta` indicates how much the device has been rotated around the X
+ * axis, or how much it is tilted from front to back. `gamma` indicates how
+ * much the device has been rotated around the Y axis, or how much it is tilted
+ * from left to right.
+ *
+ * For most browsers, the `alpha` value returns the compass heading so if the
+ * device points north, it will be 0. With Safari on iOS, the 0 value of
+ * `alpha` is calculated from when device orientation was first requested.
+ * ol.DeviceOrientation provides the `heading` property which normalizes this
+ * behavior across all browsers for you.
+ *
+ * It is important to note that the HTML 5 DeviceOrientation specification
+ * indicates that `alpha`, `beta` and `gamma` are in degrees while the
+ * equivalent properties in ol.DeviceOrientation are in radians for consistency
+ * with all other uses of angles throughout OpenLayers.
+ *
+ * To get notified of device orientation changes, register a listener for the
+ * generic `change` event on your `ol.DeviceOrientation` instance.
+ *
+ * @see {@link http://www.w3.org/TR/orientation-event/}

+ * It is possible to store more than one geometry on a feature using attribute
+ * properties. By default, the geometry used for rendering is identified by
+ * the property name `geometry`. If you want to use another geometry property
+ * for rendering, use the `setGeometryName` method to change the attribute
+ * property associated with the geometry for the feature. For example:
+ *
+ * ```js
+ * var feature = new ol.Feature({
+ * geometry: new ol.geom.Polygon(polyCoords),
+ * labelPoint: new ol.geom.Point(labelCoords),
+ * name: 'My Polygon'
+ * });
+ *
+ * // get the polygon geometry
+ * var poly = feature.getGeometry();
+ *
+ * // Render the feature as a point using the coordinates from labelPoint
+ * feature.setGeometryName('labelPoint');

+ * 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.Map({
+ * 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.
