Googlmapper: Cornford\Googlmapper\Mapper::map() should not be called statically

I use laravel 5.1 and when need to use Googlmapper i see this an error
Non-static method Cornford\Googlmapper\Mapper::map() should not be called statically, assuming $this from incompatible context

Note:i did some of changes in my app.php file to be comptable with laravel 5.1 Instead of 'Cornford\Googlmapper\MapperServiceProvider' Cornford\Googlmapper\MapperServiceProvider::class

And the Same thing in Facade aliases Any Suggestions

Thanks for your time and thanks for this awesome API
