the problem is that client code is forced to define this methods but it's bad practive because it should be necessasry if client doesn't want to.
we have
```
protected abstract onMouseOver(): void;
protected abstract onMouseOut(): void;
protected abstract onMouseMove(): void;
protected abstract onMouseClick(): void;
```
in index.ts
the problem is that client code is forced to define this methods but it's bad practive because it should be necessasry if client doesn't want to.
it's wrong becuse there is code
```
this.overlay
.on('mouseover', this.onMouseOver.bind(this))
.on('mouseout', this.onMouseOut.bind(this))
.on('mousemove', this.onMouseMove.bind(this))
.on('click', this.onMouseClick.bind(this))
```
which required this methods to exist
my motivation for this because it breacts bar-pod and others which not implements onClick added here: 493d52629c
