* @miniclass Icon.Default (Icon)

* @section
*
* A trivial subclass of `Icon`, represents the icon to use in `Marker`s when
* no icon is specified. Points to the blue marker image distributed with Leaflet
* releases.
*
* In order to customize the default icon, just change the properties of `L.Icon.Default.prototype.options`
* (which is a set of `Icon options`).
*
* If you want to _completely_ replace the default icon, override the
* `L.Marker.prototype.options.icon` with your own icon instead.
