@author: github/wolverinn
@date: 07/29/2018
requirements: only Python 3
功能:实时显示计算机上传和下载速度
function: Show the upload & download speed of the computer in real time
待改进：
- 颜色不可自定义
- 少数操作略显不流畅
- 调整窗口布局可以改进
- 没有流量统计功能
TODO:
- Support self-define color
- Some operations are not smooth
- "Adjust position" can be improved
- Don't have the function for traffic statistics
(本来生成exe的时候只想生成单个文件，但pyinstaller貌似-F -w同时使用的话生成的GUI程序无法调用os.popen())
