Swig Python3.x示例代码中文翻译及Makefile修订
由于项目需要（使用python作为封装代码，使用cpp编写程序核心代码），最近学习了如何使用swig。在此过程中，除了在博客园看到官方文档的中文翻译外，未看到其他有用的中文资料。因此我翻译了官方提供的示例代码（中的注释），并重写了Makefile以便编译。
在子文件夹中使用make编译后即可看到示例代码runme.py的输出内容，使用make clean即可清除编译过程中生成的中间文件。
请确保你已经实现安装了make和gcc。
Chinese (simple) translation of Swig Python3.x example codes and modification of Makefile.
Recently, I learned how to use swig in python due to project's need which is to write wrapping codes with python and core codes with cpp. During this process, howerver, I did not find any useful information in Chinese except translation of official documents. So here I translate those official example codes provided by siwg and modificate Makefile to make sure they can be compiled successfully.
After running make in subdirectory, you can see the outputs of 'runme.py'. You can also clean all tempotary files produced during compiling process by running make clean.
Please make sure you have installed make and gcc beforehand.
