/*
* @class Evented
* @aka L.Evented
* @inherits Class
*
* A set of methods shared between event-powered classes (like `Map` and `Marker`). Generally, events allow you to execute some function when something happens with an object (e.g. the user clicks on the map, causing the map to fire `'click'` event).
*
* @example
*
* ```js
* map.on('click', function(e) {
* alert(e.latlng);
* } );
* ```
*
* Leaflet deals with event listeners by reference, so if you want to add a listener and then remove it, define it as a function:
*
* ```js
* function onClick(e) { ... }
*
* map.on('click', onClick);
* map.off('click', onClick);
* ```

*
