Custom easing functions aren't used

[jason-jukedeck]

The Readme says a custom easing function can be passed in the config object, but it doesn't seem to get used.

Checked the source and I don't see anything that could support a custom easing function.

Am I going mad?

Here is my example.

var svg = new Walkway({
    selector: '#my-svg',
    duration: duration,
    easing: function(t) {
        console.log('never gets called');
        return t;
    }
});
