{{alias}}( start, stop[, N][, options] )
    Returns an iterator which returns evenly spaced dates over a specified
    interval.

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

    Parameters
    ----------
    start: integer|string|Date
        Starting date either as a `Date` object, JavaScript timestamp, or a date
        string (inclusive).

    stop: integer|string|Date
        Stopping value either as a `Date` object, JavaScript timestamp, or a
        date string (inclusive).

    N: integer (optional)
        Number of values. Default: 100.

    options: Object (optional)
        Function options.

    options.round: string (optional)
        Specifies how sub-millisecond times should be rounded. Must be one of
        the following: 'floor', 'ceil', or 'round'. Default: 'floor'.

    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.

    Examples
    --------
    > var t1 = new Date();
    > var it = {{alias}}( t1, new Date( t1.getTime()+86400000 ) );
    > var v = it.next().value
    <Date>
    > v = it.next().value
    <Date>
