* 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.
*
* Internally, an instance of RuntimeContainer will be used for the actual class resolution. This class uses reflection
* to instantiate classes and figure out dependencies, so there's no need for explicit class registration.
* When running the unit tests suite this will be replaced with an instance of TestingContainer,
* which provides additional functionality.
