* Action is the base class for all controller action classes.
*
* Action provides a way to divide a complex controller into
* smaller actions in separate class files.
*
* Derived classes must implement a method named `run()`. This method
* will be invoked by the controller when the action is requested.
* The `run()` method can have parameters which will be filled up
* with user input values automatically according to their names.
* For example, if the `run()` method is declared as follows:
*
* ~~~
* public function run($id, $type = 'book') { ... }
* ~~~
*
* And the parameters provided for the action are: `array('id' => 1)`.
* Then the `run()` method will be invoked as `run(1)` automatically.
