/**
 * Class AbstractEntityRepository
 *
 * This provides a base class that handles instantiating the correctly configured EntityRepository and provides an
 * extensible baseline for further customisation
 *
 * We have extracted an interface from the standard Doctrine EntityRepository and implemented that
 * However, so we can add type safety, we can't "actually" implement it
 *
 * We have also deliberately left out the magic calls. Please make real methods in your concrete repository class
 *
 * Note, there are quite a few PHPMD warnings, however it needs to respect the legacy interface so they are being
 * suppressed
 *
 * @package EdmondsCommerce\DoctrineStaticMeta\Entity\Repositories
 * @SuppressWarnings(PHPMD.TooManyPublicMethods)
 * @SuppressWarnings(PHPMD.ExcessivePublicCount)
