*
* Listeners will be called with a reference to an event object. The
* properties of this event depends on exactly what happened.
*
* All event objects have at least the following properties:
* - *object* {Object} A reference to layer.events.object.
* - *element* {DOMElement} A reference to layer.events.element.
*
* Supported map event types:
* - *loadstart* Triggered when layer loading starts.
* - *loadend* Triggered when layer loading ends.
* - *loadcancel* Triggered when layer loading is canceled.
* - *visibilitychanged* Triggered when layer visibility is changed.
* - *beforefeatureadded* Triggered before a feature is added. Listeners
* will receive an object with a *feature* property referencing the
* feature to be added.
* - *featureadded* Triggered after a feature is added. The event
* object passed to listeners will have a *feature* property with a
* reference to the added feature.
* - *featuresadded* Triggered after features are added. The event
* object passed to listeners will have a *features* property with a
* reference to an array of added features.
* - *featureselected* Triggered after a feature is selected. Listeners
* will receive an object with a *feature* property referencing the
* selected feature.
* - *featureunselected* Triggered after a feature is unselected.
* Listeners will receive an object with a *feature* property
* referencing the unselected feature.
