Fixed bug where features were regenerated with each call.
Updated uspc patents to be an iterable (like cpc patents). This was causing an problems before.
Updated PatentPipeline to fix next on empty exceptions (again).
Updated PatentRegularizer to make it properly lazy. Should no longer have as many OOM errors.
Made patent filters more verbose when they reject something. Added filters for uspto patent formats.
Removed generated tex files and added them to gitignore so they won't come back.
