ANN: monadLib 3.0.0

Hello, I have placed a new version of 'monadLib' on its web-page: http://www.csee.ogi.edu/~diatchki/monadLib Some of the changes compared to the previous version: * The whole library is in a single module MonadLib.hs (~500 lines) * Simpler and more symmetric API * Removed the (generic) monadic combinators * Removed the search transformer (may add another version of it at some point) * Rewrote some transformers in the "traditional" way (e.g., exceptions and output) * There is an optional module that defines base monads corresponding to each transformer. Comments are very welcome. -Iavor
