Function interleaved_ordered::interleave_ordered

pub fn interleave_ordered<A, B>(
    a: A, 
    b: B
) -> InterleaveOrdered<A::IntoIter, B::IntoIter> where
    A: IntoIterator,
    B: IntoIterator<Item = A::Item>, 

Interleave two ordered iterators, yielding a new iterator whose items are also ordered.
