{{alias}}( shape[, options] )
    Returns an iterator which returns indices for use indexing into an ndarray
    having a specified shape.

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

    Parameters
    ----------
    shape: Array<integer>
        Input shape.

    options: Object (optional)
        Options.

    options.order: string (optional)
        Index iteration order. By default, the returned iterator iterates over
        the last dimensions first, thus corresponding to iteration over
        contiguous data stored in row-major order. Must be either 'row-major'
        or 'column-major'.

    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 x = {{alias:@stdlib/ndarray/array}}( [ [ 1, 2 ], [ 3, 4 ] ] );
    > var it = {{alias}}( x.shape );
    > var v = it.next().value
    [ 0, 0 ]
    > v = it.next().value
    [ 0, 1 ]
