Doctrine, Twig, Symfony Form integration with Slim 4

Hi there,

I am one of the biggest funs of slim, but unfortunately, in reality I am continuously forced to do different projects in Symfony. Recently I had some spare time and (not because I needed, but just wanted) decided to integrate few Symfony components along with PHP-DI, and Doctrine to find out if it can actually work toegether properly (especially Twig+Form+Validation).


What a surprise, it actually works and I wish to share with you the results, as a prove that actually Slim is not only kind of api skeleton, but it can serve as a base for much bigger chalenges. I am very curious of any remarks and suggestions.
