[Edu-sig] Bernoulli Numbers (a generator)

[kirby urner]

Just adding to what's on file, not sure this is a "must have" but it's
fun to do, especially given the association of Bernoulli Numbers with
"the first computer program" as scoped out in Ada's notes:

According to Wikipedia, this is similar to what Knuth recommends i.e.
we're staying with integer operations, although I'm using the Fraction
type to output results (Bernoulli numbers are fractions with lots of
digits once you get into 'em, ideal grist for the mill when learning
about Python generators).
