/**
* The EntityManager is the central access point to ORM functionality.
*
* It is a facade to all different ORM subsystems such as UnitOfWork,
* Query Language and Repository API. Instantiation is done through
* the static create() method. The quickest way to obtain a fully
* configured EntityManager is:
*
* use Doctrine\ORM\Tools\ORMSetup;
* use Doctrine\ORM\EntityManager;
*
* $paths = ['/path/to/entity/mapping/files'];
*
* $config = ORMSetup::createAttributeMetadataConfiguration($paths);
* $connection = DriverManager::getConnection(['driver' => 'pdo_sqlite', 'memory' => true], $config);
* $entityManager = new EntityManager($connection, $config);
*
* For more information see
* {@link http://docs.doctrine-project.org/projects/doctrine-orm/en/stable/reference/configuration.html}
*
* You should never attempt to inherit from the EntityManager: Inheritance
* is not a valid extension point for the EntityManager. Instead you
* should take a look at the {@see \Doctrine\ORM\Decorator\EntityManagerDecorator}
* and wrap your entity manager in a decorator.
