Function sauron_vdom::diff_with_key

pub fn diff_with_key<'a, T, ATT, EVENT, MSG>(
    old: &'a Node<T, ATT, EVENT, MSG>, 
    new: &'a Node<T, ATT, EVENT, MSG>, 
    key: &ATT
) -> Vec<Patch<'a, T, ATT, EVENT, MSG>> where
    MSG: 'static,
    EVENT: 'static,
    T: PartialEq,
    ATT: PartialEq + Ord + ToString + Clone, 

Given two Node's generate Patch's that would turn the old virtual node's real DOM node equivalent into the new Node's real DOM node equivalent.
