, _(*1)

Command dispatcher that integrates with league/container., _(*2)

## Writing a command

``` php
class MyCommand
{
    /**
     * @var User
     */
    private $user;

    /**
     * You can add any arguments you need to the constructor
     */
    public function __construct(User $user)
    {
        $this->user = $user;
    }

    /**
     * The command must have a handle method.
     * Any dependencies for the handle method will be automatically resolved by the container
     * Whatever you return here will be returned by the dispatch call
     */
    public function handle(EmailSender $mailer, Logger $logger)
    {
        // Your code goes here
        $result = $mailer->sendWelcomeEmail($user);
