Provides an easy leaflet.js wrapper for react, so that you can initialize a map as a React-component:
<Map lat="60.0" lon="10.0" zoom="10"/>
function (element) {
var map = L.map(element);
L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
attribution: '© <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
}).addTo(map);
return map;
}
