New way of making widget

Hi everyone,

I am looking at the ProgressCircle widget (on github: https://github.com/mendixlabs/progress-circle )

It's amazing that this widget doesn't follow the normal structure of widget (the one has "update", "uninitialized" ... functions), and it's not in bundled widget.js.

And It till works very nice.

Do you know any extra information about this way of creating mendix widget?

Best regards,
