Happy New Years

Happy 2016 everyone.  New years threw me off my game so I missed my updates.  So I'm going to make up for that with a veritable deluge of information including the first bits of Addendum 0: Drills.  To that end I'm creating a new data tag "drills" for anything that you can practice yourself in the future.  Anyways.  Short post as an update.  Onward.  Also, for new years, I'm going to start trying to add diagrams.  It may mean fewer posts or less text, but hopefully it makes things easier to read.
