Any, All predicates (and vector operations for free)

Using generators and the new module, itertools, was the fastest version
I could finally do.  Search for "predicates" in the Vaults (when they
get updated), at the end of the tests I included some benchmarking code.
Using All starts off at about 40% more time than doing everything
in-place, and it gets worse as expressions get complex; however, it's
fun, and when you don't care much for the utmost speed, I believe it can
be didactical (at least for newbies :)

Cheers, Python lovers!
