* Generate Jekyll-compatable .md files from BibTeX file
*   - one file per year
*   - one file per type of publication
*   - single file with full BibTex entries and anchor ids for linking
*   - single file with recent publications (since 2020)
*   - single file with award publications (look for keyword=award)
* Based on BibtexRef plugin for PmWiki, https://www.pmwiki.org/wiki/Cookbook/BibtexRef
