### Extending the Decorator

As of 1.2.x I have added in a decorator object. This object takes care of turning an object that has `PresentableInterface` into a `Presenter`.
By default, this is done with Laravel's `View` objects. The reasoning behind a new class instead of the previous implementation is so it can be better tested and also to allow you to extend it.

By default, this is done with Laravel's `View` objects. The reasoning behind a new class instead of the previous implementation is so it can be better tested and also to allow you to extend it.
Here is an example of extending the `Decorator` so that instead of using the `PresentableInterface` and `getPresenter()` method you can use a public variable on the object called `$presenter`.

Note: these instructions are for Laravel usage.
