                                               TextParser.hs 
  Added files:
    libraries/HaXml/src/Text/ParserCombinators PolyState.hs 
  Log:
  Separate out a set of parser combinators with a running state
  (PolyState) from those without any state (Poly).  The two sets are
  nearly identical - the names are the same, but their types are simpler.
  
  Add new combinator to both sets: oneOf'.  It is like oneOf, but if all
  the alternatives fail, it collects all the error messages and presents
  them together, rather than throwing them away in favour of a single
  general message.
  
  There are also new combinators in the TextParser module, primarily to
  improve error messages, dealing with multiple Haskell-style
  constructors.
