Smash data into two separate modules: sets and times. I never liked

that name anyway.

Set has been extended somewhat. The comparision operators really only
work properly with Python 2.1, due to the limitations of __cmp__.
Set also uses the binary operators (&, |, ^), since these make somewhat
more sense than the arithmetic ones, though there is no good analog for
- (if only there were a nand operator...)

Bump the version to 0.9.0b3. This is not the actual 0.9.0b3 release yet,
however. I want to do some more insanity checking. But almost ready for
some candidate releases.
