From sketch to physics world and vice versa

The java code ([PBox2D][pbox2d] inherits this from [Box2DProcessing][pbox2d])
### public float scaleToProcessing(float val) ###

```java
public float scaleToProcessing(float val) {
        return val * scaleFactor;
}
```

### Ruby usage ###
Use camel case

```ruby
scale_to_processing(val)
```
