In Rust Binder I need to be able to determine whether a red/black tree is empty. Thus, add a method for that operation to replace rbtree.iter().next().is_none() This is terrible, so add a method for this purpose. We do not add a RBTree::len method because computing the number of elements requires iterating the entire tree, but checking whether it is empty can be done cheaply.
