/**
 * @classdesc
 * Abstract base class; normally only used for creating subclasses and not
 * instantiated in apps.
 * Most non-trivial classes inherit from this.
 *
 * This extends {@link module: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 module:ol/Map~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 module:ol/View~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 module:ol/Object~BaseObject#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').
