Move 2015-specific code to its own folder.

Known issues:
  -I didn't change the namespace for it, but I am open to discussion
   on doing that in a separate change.
  -There are a couple of files which should get split out into
   year-specific and not-year-specific files to reduce how much needs
   to get copied around each year still.
  -The control loop python code doesn't yet generate code with the
   right #include etc paths.
