Finally, a bunch of stuff:

* Added research PDFs
* Added more sample data from the Article Search API
* Added a Flask app that does the NYT Article Search API queries and uses cache files if available (for both the full API results, which take a while to get, and the reduced data files we use in the browser, which aren't so bad)
* The cache files in flask/static/cache/ArticleSearch correspond to the query for fp=persons:("Obama, Barack")

Finally, note that there are several files containing cached data and credentials (such as my NYT Article Search API key) which should be removed from the repository in the future.
Whoops, quick update to a cache file and the Python script used to generate it.
