Revision history for Perl extension GraphViz2.

1.00  Wed Jun  1 14:26:00 2011
	  - This is a re-write of GraphViz. The method parameter lists are incompatible.
	  	Sorry, but it now supports all options and attributes in Graphviz V 2.23.6.
	  - Rewrite GraphViz, GraphViz::Data::Grapher, GraphViz::Parse::RecDescent, GraphViz::Parse::Yacc and GraphViz::Parse::Yapp.
	  	The core code of *::RecDescent, *::Yacc and *::Yapp has been copied from GraphViz, with tiny changes.
	  - GraphViz2::Data::Grapher uses Tree::DAG_Node to hold information, before calling external plotting programs.
	  	The tree is available for you to process whether or not you actually plot the graph.
	  - GraphViz::Regex renamed GraphViz2::Parse::Regexp.
	  - GraphViz::XML renamed GraphViz2::Parse::XML. And it uses XML::Tiny by default.
	  	One demo shows how to use XML::Bare instead.
	  - All new documentation.
	  - All new demos, in scripts/*.pl. These are documented in GraphViz's POD.
	  - All demo output included, in html/*.html and html/*.svg.
