too-many-instance-attributes (R0902):
Too many instance attributes (7) Used when class has too many instance
attributes, try to reduce this to get a simpler (and so easier to use) class.

Many of our functions have 8 or more, so turn this off.

too-few-public-methods (R0903)
Too few public methods (%s/%s) Used when class has too few public methods,
so be sure it's really worth it.

Many of our classes have 0 public methods due to the way that our C is
imported.
