{{alias}}( α, β[, options] )
    Returns an iterator for generating pseudorandom numbers drawn from a gamma
    distribution.

    If an environment supports Symbol.iterator, the returned iterator is
    iterable.

    The function throws an error if `α <= 0` or `β <= 0`.

    Parameters
    ----------
    α: number
        Shape parameter.

    β: number
        Rate parameter.

    options: Object (optional)
        Options.

    options.prng: Function (optional)
        Pseudorandom number generator (PRNG) for generating uniformly
        distributed pseudorandom numbers on the interval `[0,1)`. If provided,
        the `state` and `seed` options are ignored. In order to seed the
        returned iterator, one must seed the provided `prng` (assuming the
        provided `prng` is seedable).

    options.seed: integer|ArrayLikeObject<integer> (optional)
        Pseudorandom number generator seed. The seed may be either a positive
        unsigned 32-bit integer or, for arbitrary length seeds, an array-like
        object containing unsigned 32-bit integers.

    options.state: Uint32Array (optional)
        Pseudorandom number generator state. If provided, the `seed` option is
        ignored.

    options.copy: boolean (optional)
        Boolean indicating whether to copy a provided pseudorandom number
        generator state. Setting this option to `false` allows sharing state
        between two or more pseudorandom number generators. Setting this option
        to `true` ensures that a returned iterator has exclusive control over
        its internal state. Default: true.

    options.iter: integer (optional)
        Number of iterations.

    Returns
    -------
    iterator: Object
        Iterator.

    iterator.next(): Function
        Returns an iterator protocol-compliant object containing the next
        iterated value (if one exists) and a boolean flag indicating whether the
        iterator is finished.

    iterator.return( [value] ): Function
        Finishes an iterator and returns a provided value.

    iterator.PRNG: Function
        Underlying pseudorandom number generator.

    iterator.seed: Uint32Array|null
        Pseudorandom number generator seed.

    iterator.seedLength: integer|null
        Length of generator seed.

    iterator.state: Uint32Array|null
        Generator state.

    iterator.stateLength: integer|null
        Length of generator state.

    iterator.byteLength: integer|null
        Size (in bytes) of generator state.

    Examples
    --------
    > var it = {{alias}}( 1.0, 1.0 );
    > var r = it.next().value
    <number>
    > r = it.next().value
    <number>
