Design patterns and best practices

Thanks for this project :) It's would be interesting to add exercices/examples about design patterns and principles like SOLID, KIss, ACID?

@kevin-schmitt Thanks for showing interest!

It's a great idea, and any PR's are welcome. Currently, I don't have enough personal time for any additions, any help is appreciated.

@azdanov thanks, No problem i beginning to work on this :) Edit: I push pull request for chain of responsability pattern exercice :) #37
