Let me add a bit of additional info to this... I indicated that you
should implement methods `next` and `reset` on your wrapper. This is
not a hard requirement.

You _do_ need to provide a way to access a particular generator's
(i.e. wrapper's) next number, and provide a way to reset the sequence.
For a class wrapper, this is somewhat natural to do as methods `next`
and `reset`, hence my suggestion.

However, if you find want to use another technique (function, code
block, closure, etc.) is more suitable for your solution, please do...
and if that means providing alternate means (other than next/reset
methods) to access the next random number and reset the sequence,
that's fine. Just state in your submission how you provided for next/
reset equivalents.
