Version 0.1 Base version of pybib2web: Parse .bib BibTeX files and output HTML. This tries to mimic the overall behavior of [bibtex2html](https://sourceforge.net/projects/bibtex2html/), but uses more structured HTML (e.g., more classes and ids for manual CSS layouting). Script `contrib/check-doi` for checking the DOIs of BibTeX entries. check-doi makes sure that DOIs listed in .bib BibTeX files are available online, and downloads all available metadata through https://www.crossref.org/.
