unmarked as a Work In Progress

@all Ready for review.

@mkuhn I changed a "bit" your code to avoid multiple function calls, and especially to change a bit the loops when I could. I didn't put the full detailed interface (!1 (closed)) as it became a total mess when I tried to do it. I'm not sure it's worth doing it. Is this interface enough ? or should we provide something more detailed ? I would say, it's fine like this.
