group papers by subareas

[k4rtik]

"group things by subareas: Languages, Verification, Semantics, Models, etc. (Surveys doesn't really fit with the above but would also be a nice filter.)" using categories and tags.

Also categorize these better: https://quantumpl.github.io/bib/publication/#0 (such as into software and talks, etc)

Categories added so far can be seen here: https://quantumpl.github.io/bib/categories/

Some tips for keywords: https://carleton.ca/webservices/2010/singular-versus-plural-keyword-and-tagging-vocabulary-best-practices/

A simple rule that satisfies the overall goal of natural-sounding tags is when tagging an item, simply complete the following sentence “This item is about __________.” This rule is consistent with all guidelines.
