Returns an object representing a negative binomial distribution with
given parameters `size` and `prob`.  The object has
properties `d`, `p`, `q`, `r`.

`size` must be strictly positive, and `prob` must be in `(0, 1]`.

```
nbinom(size, prob).d(x, logp)            // same as dnbinom(size, prob, logp)(x)
nbinom(size, prob).p(x, lowerTail, logp) // same as pnbinom(size, prob, lowerTail, logp)(x)
nbinom(size, prob).q(x, lowerTail, logp) // same as qnbinom(size, prob, lowerTail, logp)(x)
nbinom(size, prob).r()                   // same as rnbinom(size, prob)()
```
