"""
A python script to modify bib data and
to display references with specific bibliography standard
features：
1. souce map of biblatex like: generalize date
bib文件数据修改，比如对日期进行规范化等
2. bib file parsing, bib file out, json formatted file out
bib文件解析，输出新的bib文件，或json格式的文件
3. display the bib info with specific standard like GB/T 7714-2015
将bib文件信息格式化显示，比如以GB/T 7714-2015格式显示
4. 当某些项缺失时，后面跟着的项前标点可能会变化的问题，要处理。
5. newspaper,与aritcle的关系
6. standard,与book和inbook的关系
7. 同样是date，newspaper需要写全，而article不需要。
