new GroupFireBolt()
This class is responsible for dispatching any behavioural action to all the visual units housed by the canvas.
It is created by Canvas. This class does not handle any physical actions. Physical actions get triggered
in VisualUnit which is managed by it's own firebolt instance. The firebolt instance of canvas only
propagates the action to all the visual units in it's composition.
To get the firebolt instance of Canvas
```
const firebolt = canvas.firebolt();
```
