new move to Pimple 3.0.0 with possible extension brought to us by pickle

we will probably want to stay away from symfony DIC since it has so many hidden dependencies https://github.com/symfony/symfony/blob/master/src/Symfony/Component/DependencyInjection/composer.json#L21-L29 and the ones that branch out from those. We definitely want pimple.

The reason why i asked about this yaml configuration feature is I thought i saw that done with just pimple.
