{{alias}}( iterator )
    Returns an iterator which iteratively computes a cumulative mid-range.

    The mid-range is the arithmetic mean of maximum and minimum values.
    Accordingly, the mid-range is the midpoint of the range and a measure of
    central tendency.

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

    Parameters
    ----------
    iterator: Object
        Input iterator.

    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 arr = {{alias:@stdlib/array/to-iterator}}( [ 2.0, -5.0, 3.0, 5.0 ] );
    > var it = {{alias}}( arr );
    > var v = it.next().value
    2.0
    > v = it.next().value
    -1.5
    > v = it.next().value
    -1.0
    > v = it.next().value
    0.0
