Revision history for Perl extension Graph::Easy::Marpa.

1.00  Tue Jul 19 15:42:00 2011
	  - Implement subgraphs (i.e. groups), classes and subclasses. See the FAQ for notes on group attributes.
	  - Put a copy of the CSV version of the STT in the __DATA__ section of the lexer, to speed up reading it.
	  - Support the rankdir option for the graph as a whole.
	  - Support the directed option for the graph as a whole.
	  - In Graph::Easy::Marpa::Lexer, use the timeout feature to ensure the DFA does not loop forever.
	  - In Graph::Easy::Marpa::Lexer, make OpenOffice::OODoc optional, and only load it if the user specifies *.ods
	  	for the STT file.
	  - In Graph::Easy::Marpa::Lexer, add verbose to the list of keys accepted by new().
	  - In Graph::Easy::Marpa::Renderer::GraphViz2, handle cases where the graph definition starts or ends with an edge,
	  	or a daisy chain of edges.
	  - In Graph::Easy::Marpa, add a new section to the docs, Methods, where all public methods are documented.
	  	These are the same as the parameters to new(), along with log() and run().
	  - In other modules, update the lists of keys acceptable to new(), and the corresponding method docs.
	  - Allow an object of type Graph::Easy::Marpa to pass a logger object to objects of type Graph::Easy::Marpa::Lexer
	  	and of type Graph::Easy::Marpa::Parser, along with the corresponding values for maxlevel and minlevel.
	  - Use Date::Format to add a date stamp at the end of html/index.html, as output by generate.index.pl.
	  - Extend demo with data/edge.08.raw, which show various arrow heads, and many class and subgraphs samples too.
	  - Export the STT (cvs file) as data/default.stt.html. The version shipped with 0.91 was not up-to-date.

0.91  Wed Jun 29 11:41:00 2011
	  - Update pre-requisites. Set::FA 1.05 -> 1.06. Add File::Spec, File::Basename, GraphViz2.

0.90  Tue Jun 28 12:18:00 2011
	  - Allow spaces in graph definitions, by expanding the regexps in the state transition table.
	  - Add more sample data, as data/*.raw (for input to the lexer) and data/*.cooked (as output from the lexer
	  	and input to the parser).
	  - Adopt Set::Array instead of manually managing some arrayrefs.
	  - Ensure all major methods (normally run() ) return 0 for success and 1 for failure, and that test code does too.
	  - Switch from Moose to Hash::FieldHash, to make the code more light-weight.
	  - Implement scripts/generate.index.pl to create a web page with embedded Graph::Easy files and corresponding *.svg files.
	  - Upload demo to http://savage.net.au/Perl-modules/html/graph.easy.marpa/index.html.

0.60  Sat May 14 11:16:00 2011
	  - Implement basic Graph::Easy::Marpa::Lexer to read raw Graph::Easy files.
	  - Change Graph::Easy::Marpa::Test.run() to test_parser(), and implement test_lexer().
	  - Change Graph::Easy::Marpa::Test to accept file name not file number.
	  - Add various test files in data/ and t/.
	  - Add scripts/graph.30.sh to show how to feed the lexer's output to the parser.

0.51  Wed Apr 27 10:46:00 2011
	  - Update pre-reqs.

0.50  Tue Apr 26 11:09:44 2011
