* Version 3.4.9, in addition to implementing __iadd__, also includes a
significantly faster implementation for __add__. For extending a given
instance of BitVector, the implementation for __iadd__ adds bits to the
existing instance as opposed to creating a new instance. These changes
to the module should make it easier to solve larger problems more
quickly with BitVector.
