@hackage reactivity0.3.0.0

An alternate implementation of push-pull FRP. This is based on the Reactive package (http:/haskell.orghaskellwiki/reactive) (and the sources have been made available in accordance with the GPL [license] of that package).

Known problems with this version:

• The UI library tends to freeze after a few seconds of use. Don't know whether the problem is semantical or a deadlock. The core library works correctly though.

• There seems to be a speed problem that I can't identify, but it doesn't appear to be fundamental.

• UI library is currently on Windows only, but there are plans....
