* In case anything went wrong during the execution you should throw an exception to make sure the user will get a
* useful error message and to make sure the command does not exit with the status code 0.
*
* Ideally, the actual command is quite short as it acts like a controller. It should only receive the input values,
* execute the task by calling a method of another class and output any useful information.

* Execute the command like: ./console queuedtracking:test --name="The Piwik Team"
