Clean Architecture Simple App

This repo contains a simple command line tool and a rest server that checks the best price between two destinations.

Architecture

For the system architecture I have decided to use the Clean Architecture proposed by Robert C. Martin (Uncle Bob).

Pull requests are welcome.
