FeatureGroup

Extended LayerGroup that makes it easier to do the same thing to all its member layers:

• bindPopup binds a popup to all of the layers at once (likewise with bindTooltip)
• Events are propagated to the FeatureGroup, so if the group has an event handler, it will handle events from any of the layers. This includes pointer events and custom events.
• Has layeradd and layerremove events

Usage example

new FeatureGroup([marker1, marker2, polyline])
.bindPopup('Hello world!')
.on('click', function() { alert('Clicked on a member of the group!'); })
.addTo(map);
