Minor update.

Dependency injection. (Allowed Snappy to be injected into the class if I require the class as a dependency in my controller/service)

Added/updated some doc blocks on variables and constructor.

Update CS to Laravel Coding Guidelines https://github.com/laravel/framework/blob/master/CONTRIBUTING.md#coding-guidelines

Added some shortcuts rather then 'loadHtml', 'loadFile' and 'loadView' you can use 'hmtl', 'file' and 'view'.

Ability to get snappy instance on method 'snappy'.

Removed unused rendered variable.

I was going to use the Event dispatcher and fire events for generating the PDF.
