Add recursion and tail call recursion to Eluids Eggs

It's true that this one uses tail call recursion, but I think we were trying to keep it low on the concept tree. If we add tail recursion as a prerequisite, it won't be available very soon.
Anyway, I don't really have a problem with it, I just remembered this is something that was discusses. I'll approve and leave it up to you :)

Hmmm, do you know where was this chat on keeping it low on the concept tree? And is there any reason for that?
It looks like a great practice exercise for recursion, it's simple and nearly all the complexity is in the recursive bit

Here it is. OK I'll be honest it, if was more of a single comment than a chat 😛

I'm not saying this is not a great exercise for recursion, it sure is, it just move the exercise deeper in the tree. But yes, you're right, if you don't know what recursion is, you won't be able to solve this exercise properly, let's merge this.
