Trait unicycle::PollNext

pub trait PollNext {
    type Item;
    fn poll_next(
        self: Pin<&mut Self>, 
        cx: &mut Context
    ) -> Poll<Option<Self::Item>>;
}

Trait for providing a poll_next implementation.

This is like the lightweight unicycle version of the Stream trait, but we provide it here so we can shim in our own generic next implementation.
