I'm still not sure if I'd like to keep an Array as a parameter, I was thinking about using something like computeGroup( [ ... ] ), or something along those lines. If we have a class we would have more control over the process.

I think for now it's fine, but it's something to discuss later. Just want to update the labels for now.
