what can I put there to describe what I've did?

Seriously; I'm confusing about a good title for this PR. Please: **tips**.

– I really think the variable [`$homes`](https://github.com/malukenho/speaknumber/blob/master/src/Speak/Number.php#L64) is named incorrectly when we're talking in a mathematical context.
– What about expand the current streak to accept [any](https://github.com/malukenho/speaknumber/blob/master/src/Speak/Number.php#L28-L30) length? of course, 4 is very, very, very limited.

I think I can make a PR for that, if there's an agreement about those proposals. Or we can work together.

Thanks,
Hugs.
