/**
* ArgvInput represents an input coming from the CLI arguments.
*
* Usage:
*
* $input = new ArgvInput();
*
* By default, the `$_SERVER['argv']` array is used for the input values.
*
* This can be overridden by explicitly passing the input values in the constructor:
*
* $input = new ArgvInput($_SERVER['argv']);
*
* If you pass it yourself, don't forget that the first element of the array
* is the name of the running application.
*
* When passing an argument to the constructor, be sure that it respects
* the same rules as the argv one. It's almost always better to use the
* `StringInput` when you want to provide your own input.
