ExponentialZoomManager

All Implemented Interfaces:

it.unibo.alchemist.boundary.wormhole.interfaces.SlideInputManager , it.unibo.alchemist.boundary.wormhole.interfaces.ZoomManager
```
public final class ExponentialZoomManager
extends AbstractSlideInputManager implements ZoomManager
                    
```
An ExpZoomManager converts the sliding of any physical/virtual device/control into a zoom rate through an exponential function (in this way I am sure to not see negative values ;-). Zoom = base ^ (amount of slides / normalization value).
