error in Hayoo.Haddock with missing signatures removed
workaround built into Hayoo.Haddock do deal with rotten Haddock source links that contain binary chars '\001' and '\002'

these occur in class methods docs e.g. in http://hackage.haskell.org/package/base-4.6.0.1/docs/Prelude.html
in Hayoo FunctionInfo a type field added for classifying the documented entry
space leak with shared bytestrings in Binary instances for compressed data types removed
