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
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
188.8.131.52. Let me know if it works or breaks on other configurations.
