实现图的深度优先, 广度优先遍历算法，并输出原图结构及遍历结果。 初步完成总体设计，搭好框架；

最低要求：两种遍历都要实现，写出画图的思路；

进一步要求：画出图的结构，有兴趣的同学可以进一步改进图的效果。

-Implementation of Depth-first, breadth-first traversal algorithm, and outputs the original image structure and the traversal result. Completed the initial design, and setting up the framework　minimum requirement: Two traversal must realize, the idea to write drawing　further requirements: Draw Graphs, interested students can further improve the pattern performance.
