How to add baseLayer ====================

What is a leaflet baseLayer : http://leafletjs.com/examples/layers-control.html

In Plone, if you want to add a baseLayer, you have to add a subscriber on collective.geo.geographer.interfaces.IGeoreferenced (for exemple, in `configure.zcml`):

    <subscriber
        for="collective.geo.geographer.interfaces.IGeoreferenced"
        provides="collective.geo.leaflet.interfaces.IMapLayer"
        factory=".maplayers.OpenStreetMap
        />

After, create your factory in python (`maplayers.py`):

    from collective.geo.leaflet.maplayers import MapLayer
    from Products.Five.browser.pagetemplatefile import ViewPageTemplateFile

    class OpenStreetMap(MapLayer):
        name = u"osm"
        title = _(u"Open Street Map")
        index = ViewPageTemplateFile('browser/layers/osm.pt')

And add your javascript into a template file `osm.pt`:

    <script type="text/javascript">
        var osmAttrib = '&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors';
        var osmUrl = 'http://{s}.tile.osm.org/{z}/{x}/{y}.png';
        var %(name)s = L.tileLayer(osmUrl, {
             attribution: osmAttrib,
        });
    </script>
