Document for new SymfonyStyle and other changes?

[weaverryan]

@javiereguiluz I haven't been watching the SymfonyStyle-related changes (the class was new in 2.7) much (though I like the pretty) - is there something we should document related to this?

[javiereguiluz]

Yes, we should document all the methods available for commands (title(), section(), table(), etc.) We are still deciding some code details (see symfony/symfony#16000) but once we settle on that and test the redesigned commands, we'll start documenting everything.

To better understand what does this new style bring, I like this analogy: so far, commands mixed "CSS" and "HTML". With this new class, commands care only about "semantic HTML" and the "CSS" is automatically applied by Symfony. The result is commands with cleaner and more concise code.

@javiereguiluz and that's exactly why I'm excited about documenting them - free, good-looking styling and less styling-stuff in your code to make it happen. thx :)

Same here - I'll feel happy if the documentation is ready.
