GraphThing 0.9.3 released

[Dave Symonds <ds@seul.org>]

Hi All,

GraphThing 0.9.3 is now available, chock full of cool little features
just in time for Christmas (http://graph.seul.org).

The following changes have been made since 0.9.2:

	+ Added full simple digraph support, including:
		digraph edge drawing and printing, with weights
	+ Eulerian tours are constructed and demonstrated
	+ Chromatic numbers are justified by demonstration, where possible
	* Large optimisations for colouring-related computations
	* Fixed matrix exponentiation for the A^0 case
	* gcc 3.2 fixes

Please have a good play with it, epecially the digraph support and the
graph colouring features. Let me know what works, and what doesn't.


Cheers,

Dave.
