extern crate xtree;
use xtree::*;
let tree =

        / (tr!(2)
            / tr!(3)
            / tr!(4))
        / tr!(5);

It will construct a tree like below

//      1
//     / \
//   2    5
//  / \
// 3   4

Depth-First iterate a tree

for value in tree.df_iter(){
    print!("{} ",value);
}

It will print 1 2 3 4 5 in console.

Breadth-First iterate a tree and Change the value

for value in tree.bf_iter_mut(){
    *value += 1;
    print!("{} ",value);
}

It will print 2 3 6 4 5 in console.

Freely visit node with Cursor

let mut cursor = tree.cursor();
