    :arg obj: The object to iterate over
    :kwarg include_string: if :data:`True`, treat strings as iterables.
        Otherwise treat them as a single scalar value.  Default :data:`False`

    This function will create an iterator out of any scalar or iterable.  It
    is useful for making a value given to you an iterable before operating on it.
    Iterables have their items returned.  scalars are transformed into iterables.
    A string is treated as a scalar value unless the :attr:`include_string`
    parameter is set to :data:`True`.  Example usage::

        >>> list(iterate(None))
        [None]
        >>> list(iterate([None]))
        [None]
        >>> list(iterate([1, 2, 3]))
        [1, 2, 3]
        >>> list(iterate(set([1, 2, 3])))
        [1, 2, 3]
        >>> list(iterate(dict(a='1', b='2')))
        ['a', 'b']
        >>> list(iterate(1))
        [1]
        >>> list(iterate(iter([1, 2, 3])))
        [1, 2, 3]
        >>> list(iterate('abc'))
        ['abc']
        >>> list(iterate('abc', include_string=True))
        ['a', 'b', 'c']
