[Haskell-cafe] ANN: atom-0.0.3

[Tom Hawkins]

I pushed out a new version of atom that incorporates some of John's
recommendations (thanks John).  And it ships with a slightly better
example.

The release also includes means to extract code coverage to track
which atom rules have fired during testing.
