/**
* Configurable is the interface that should be implemented by classes who support configuring
* its properties through the last parameter to its constructor.
*
* The interface does not declare any method. Classes implementing this interface must declare their constructors
* like the following:
*
* ```php
* public function __construct($param1, $param2, ..., $config = [])
* ```
*
* That is, the last parameter of the constructor must accept a configuration array.
*
* This interface is mainly used by [[\yii\di\Container]] so that it can pass object configuration as the
* last parameter to the implementing class' constructor.
*
* For more details and usage information on Configurable, see the [guide article on configurations](guide:concept-configurations).
