功能包括从文件中读取文章，将文章转换为哈夫曼编码，将哈夫曼编码还原，就是那几个基本算法的实现啦。

为了方便查看，这里输出的哈夫曼编码是1byte的，其实真正应该将其变为1bit存储，这样才能达到压缩的目的。-Features include articles to read from the file, the article is converted to Huffman coding, Huffman coding will be restored and that is the realization of a few basic algorithms 啦. To facilitate viewing, where the output of the Huffman code is 1byte, and in fact they really should turn it into 1bit memory, in order to achieve compression purposes.
