Suggestion for starting the Kata

[alvarogarcia7]

Hello,

first of all, thank you for the kata. It is amazing!

When I first did the kata, I didn't understand that I'm receiving a POJO to "read from the Pad".

I would suggest that the kata provides a sample POJO, to guide better the kata.

A simple suggestion:

You will receive a POJO like this one:

class UserSelection {
	$coffee = true; // or any format that you imagine. The Pad will provide that result to you, describing what the user has requested on the pad itself.
	$sugars = 2;
}

Please do let me know if you agree with this suggestion and/or whether I should send a PR with these changes.

Thanks in advance,
