I needed this quite a lot in my own code but didn't take the time to
generalize it into a releasable package. Thanks!

Data.Bimap is a data structure that represents a bidirectional mapping between two key types. A bimap has two type parameters; each value in the bimap is associated with exactly one value of the opposite type. In other words, it's a bijection between (subsets of) its argument types.
The API is loosely based on Data.Map; feedback and suggestions are most welcome.
So far I've only tested it on GHC 6.6 on Linux/x86, with Cabal 1.2.3.0. Let me know if it works or breaks on other configurations.
