feat #  prototype for section refresh animation

implementation of the section refresh animation
I would not call `this.__json.copy` here. You can just set the value with:
```js
cfg.animation = animationBind.inside[animationBind.to];
```
(and the same inside the function below).

This way, it is possible to change properties inside the original object directly and have the new values taken into account automatically. Of course, for this to work, we should not cache the transformed value in `this._animation`.
