Adding AAS 227 data as a CSV list with categories (taken from 5a92d086f52185cad1a9a2faba980203d67e8c0f). I modified that list to add subject affiliations to all of the plenary talks. Town Halls were all left in Category 7 (those have a very different format, but I think could fall under the "professional development" umbrella, if nothing else).
