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；

-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 requirements: two traversal must realize, write drawing ideas
