Function ore::graph::try_nonrecursive_dft_mut

pub fn try_nonrecursive_dft_mut<Graph, NodeId, AtEnter, AtExit, E>(
    graph: &mut Graph, 
    root: NodeId, 
    at_enter: &mut AtEnter, 
    at_exit: &mut AtExit
) -> Result<(), E> where
    NodeId: Eq + Hash + Clone,
    AtEnter: FnMut(&mut Graph, &NodeId) -> Result<Vec<NodeId>, E>,
    AtExit: FnMut(&mut Graph, &NodeId) -> Result<(), E>, 

Same as try_nonrecursive_dft, but allows changes to be made to the graph.
