{{alias}}( [options] )
    Returns an iterator which generates a Tribonacci sequence.
    
    The returned iterator can only generate the first 64 Tribonacci numbers, as
    larger Tribonacci numbers cannot be safely represented in double-precision
    floating-point format.

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


    Parameters
    ----------
    options: Object (optional)
        Function options.

    options.iter: integer (optional)
        Number of iterations. Default: 64.


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

    iterator.next(): Function
        Returns an iterator protocol-compliant
        object has 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.


    Examples
    --------
    > var it = {{alias}}();
    > var v = it.next().value
    0
    > v = it.next().value
    0
