	* lib/rgl/base.rb: Preparing for 0.4.0 release

2008-08-26 20:07  javanthropus

	* lib/rgl/dot.rb, lib/rgl/rdot.rb, tests/TestRdot.rb: Move the DOT
	  module into the RGL module

	  * This eliminates a class conflict with the DOT module from rdoc
	  when building RGL's documentation * Also remove the superfluous
	  DOT prefixes from class names in the DOT module

2008-08-24 06:16  javanthropus

	* Rakefile: Remove some comments I accidentally left in while
	  testing rdoc functionality

2008-08-24 06:03  javanthropus

	* Rakefile, lib/rgl/transitiv_closure.rb, lib/rgl/transitivity.rb,
	  tests/TestTransitiveClosure.rb, tests/TestTransitivity.rb:
	  Feature 21641: Added transitive reduction functionality

	  * Updated the gem description to announce this functionality *
	  Moved the transitive closure functionality into the
	  transitivity.rb file along with the transitive reduction
	  funtionality * Modifed the transitiv_closure.rb file to simply
	  load the transitivity.rb file for backward compatibility * Moved
	  all transitivity tests into TestTransitivity.rb

2008-08-23 15:45  javanthropus

	* lib/rgl/condensation.rb, lib/rgl/transitiv_closure.rb,
	  tests/TestTransitiveClosure.rb: Defect 21630: Fixed transitive
	  closure

	  * The fix is based on the algorithm described in the
	  documentation for the implementation of transitive closure in
	  Boost * Along with the fix, performance is improved to O(|V||E|)
	  * This implementation needs graph condensation, so that function
	  was added as well * More tests were added to cover more corner
	  cases

2008-08-23 05:40  javanthropus

	* tests/TestGraph.rb: Update basic graph tests to account for
	  graphs with edgeless vertices Also clean up some minor formatting

	* lib/rgl/dot.rb, lib/rgl/rdot.rb, tests/TestDot.rb,

	  options, and values, are now automatically quoted as necessary
	  according to the rules documented at
	  http://www.graphviz.org/doc/info/lang.html and
	  http://www.graphviz.org/Documentation/dotguide.pdf.

	  Labels are handled specially in order to account for \l, \r, and
	  \n sequences but are otherwise treated the same as other options.

	  New tests were added to confirm proper function.

	  Some changes were made in order to remove explicit quotes from
	  labels which are no longer necessary.
