/**
`<ProgressButton/>` is a special version of the `<Button/>` element that can be used to visualize a running process.
It is shown as a raised disabled button but this behaviour can be overwritten, using the `raised`
 and `disabled` paramters from the `<Button/>` element.

```js
import {ProgressButton} from '@eccenca/gui-elements';

const Page = React.createClass({
    // template rendering
    render() {
        return (
            <ProgressButton
                progress={50}
                lastUpdate={'August 31st 2017, 9:48:24 am.'}
                tooltip={'running'}
                raised={false}
            >
                Working!
            </ProgressButton>
        )
    },
    // ....
});
```

You can use `progress` option directly on `<AffirmativeButton/>`, `<DismissiveButton/>`
 and `<DisruptiveButton/>` elements.
