Missing documentation for InputArgument::IS_ARRAY

[fabpot]

InputArgument::IS_ARRAY is not documented. It can only be used at the end of the argument list and allows to take an indefinite number of arguments:

$console
    ->register('foo')
    ->setDefinition(array(
        new InputArgument('values', InputArgument::IS_ARRAY, 'An array of arguments'),
    ))
    ->setDescription('Foo')
    ->setCode(function (InputInterface $input, OutputInterface $output) {
        print_r($input->getArgument('values'));
    })
;

if run with console foo a b c d e, the argument value will be: ['a', 'b', 'c', 'd', 'e']

I just wanted to create a ticket for this too! (someone asked it on irc yesterday)

None of the options of InputArgument is documented, that should be done the same way as the InputOption options are documented in components/console/intro. But I think this deserves its own article, like the other article in components/console.

I'm pretty happy with the PR from @xabbuh that I just merged. @wouterj let me know if you can see some additional things that should be discussed.

And btw, this was great - Fabien opened an issue, Wouter commented on it, xabbuh created a PR, Wouter reviewed, xabbuh updated it, I merged it in - all within 12 hours. That's awesome!

Thanks everyone!
