Leaflet 0.3 -> 0.4 Icon API upgrade

creating-icons.js

// 0.3 way
var icon = new L.Icon('icon.png');

// 0.4 way
var icon = new L.Icon({iconUrl: 'icon.png'}); // or just "L.icon(...)"

icon-class.js

// 0.3 way

var MyIcon = L.Icon.extend({
    iconUrl: 'icon.png',
    ...
});

// 0.4 way

var MyIcon = L.Icon.extend({
    options: {
        iconUrl: 'icon.png',
        ...
    }
});

// if you need to inherit default marker properties, inherit from L.Icon.Default instead of L.Icon
