/**
* PSR11 compliant dependency injection container for WooCommerce.
*
* Classes in the `src` directory should specify dependencies from that directory via an 'init' method having arguments
* with type hints. If an instance of the container itself is needed, the type hint to use is \Psr\Container\ContainerInterface.
*
* Classes in the `src` directory should interact with anything outside (especially code in the `includes` directory
* and WordPress functions) by using the classes in the `Proxies` directory. The exception is idempotent
* functions (e.g. `wp_parse_url`), those can be used directly.
*
* Classes in the `includes` directory should use the `wc_get_container` function to get the instance of the container when
* they need to get an instance of a class from the `src` directory.
*
* Class registration should be done via service providers that inherit from Automattic\WooCommerce\Internal\DependencyManagement
* and those should go in the `src\Internal\DependencyManagement\ServiceProviders` folder unless there's a good reason
* to put them elsewhere. All the service provider class names must be in the `SERVICE_PROVIDERS` constant.
*
* IMPORTANT NOTE: By default an instance of RuntimeContainer will be used as the underlying container,
* but it's possible to use the old ExtendedContainer (backed by the PHP League's container package) instead,
* see RuntimeContainer::should_use() for configuration instructions.
* The League's container, the ExtendedContainer class and the related support code will be removed in WooCommerce 10.0.
