  Log:
  GLR extension for Happy.
  
  GLR parsing allows parsing of ambiguous grammars, to produce a directed,
  acyclic, and-or graph which compactly represents possible alternative parses.
  
  This code has been built from scratch and tested on the examples.
  
  Documentation not yet ready - will check in soon
  
  NEW:
   * examples/
      - some examples of using the parser
   * src/ProduceGLRCode.lhs
      - generates the GLR parser from templates and LR tables
   * templates/GLR_{Base,Lib}
      - driver components for the parser
  
  CHANGED:
   * src/GenUtils.lhs and src/ProduceCode.lhs
      - moved mapDollarDollar into GenUtils, and corrected bug on thd3(!)
  
   * src/Main.lhs
      - new flags added, and call the GLR parser if selected
  
   * LICENSE
      - added mention of this work.
