Setup Symfony with Nginx, PHP 7 and PostgreSQL on Ubuntu 16.04

Symfony was heavily inspired by other web application frameworks such as Ruby on Rails, Django, and Spring.
Symfony makes heavy use of existing PHP open-source projects as part of the framework, including:
- Propel or Doctrine as object-relational mapping layers
- PDO database abstraction layer
- PHPUnit, a unit testing framework
- Twig, a templating engine
- Swift Mailer, an e-mail library
