* {
* public function run();
* public function basicHelp();

* [php]
* $cli = new Doctrine\Common\Cli\CliController();
* $cliNS = $cli->getNamespace('custom');
* $cliNS->addTask('myTask', 'MyProject\Tools\Cli\Tasks\MyTask');
*
* To execute, just type any classify-able name:
*
* $ cli.php custom:my-task
