/**
 * 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\Setup;
 *     use Doctrine\ORM\EntityManager;
 *
 *     $paths = array('/path/to/entity/mapping/files');
 *
 *     $config = Setup::createAnnotationMetadataConfiguration($paths);
 *     $dbParams = array('driver' => 'pdo_sqlite', 'memory' => true);
 *     $entityManager = EntityManager::create($dbParams, $config);
 *
 * For more information see
 * {@link http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/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.
