Convert between ByteString and Vector.Storable without copying

This library allows conversion between the types from @Data.ByteString@ (package @bytestring@) and @Data.Vector.Storable@ (package @vector@) without copying the underlying data. This is useful, for example, when @ByteString@ IO produces or consumes vectors of numbers in native byte order. This trick relies on the fact that @ByteString@ and @Vector@ use their respective @ForeignPtr@s in compatible ways. It works with @bytestring-0.9.1.10@ and @vector-0.9@ on GHC 7.0. It may break with future releases of these packages. Depending on this library should be seen as a way to document and standardize an existing hack, and not as an absolute guarantee of correct behavior.
