Revision history for Perl extension CM::Permutation.

0.94 Sun Oct 23 05:26:10 EEST 2011
        - Added reset key Z to reset the cube to a solved state
        - merged from mathshell branch
        - added view angle controlled by mouse movement
        - added net representation of the cube

0.93 Fri Jul 22 10:25:30 EEST 2011
        - Separated Rubik demo code
        - Wrote Rubik game, keyboard controlled cube, moves F,U,R,B,L,D  and S scrambles the cube
        - fixed some bugs in rotate_face
        - removed SDL stuff, not needed
        - fixed some of the links in the documentation, added some more links

0.9  Mon Jul 18 06:12:47 EEST 2011
        - Switched to GLUT API from OpenGL.pm instead of the GL API, main reason was trouble with the upgrade of OpenGL package from CPAN to 0.64 
            (faces of the cubies weren't showing up because of the upgrade, switching to GLUT fixed that)
      	-  Added product group
		    -  Added tuple elements
		    -  Added tests for tuple and product group
		    -  Added some nice POD
		    -  Added factor group and commutator group
		- Added morphism class and test with first isomorphism theorem
0.4   Wed Feb 24 13:37:00 2010
        - Added Dihedral group
        - Added ModuleMultiplicativeGroup
        - Added CM::Rubik which models the rubik's cube
        - Added an OpenGL application to visualize the moves of the Rubik's cube
        - Added some more tests
0.08  Mon Jan 4  15:03:00 2010
        - Added some more documentation.
        - Added CM::Group::Altern
        - Replaced bithacks with Bit::Vector
        - Added Dimino's algorithm for computing all elements of a subgroup of S_n given its generators
          and also added tests for it
        - Added tests for normal_subgroups()
0.065 Sun Dec 13 17:00:00 2009
        - Added even_odd method for permutations
        - Added more tests

        - Added conj_classes_fast
0.051 Mon Dec 7  01:56:00 2009
        - Fixed a dependency for CPAN tests(dunno if this needs a new version, does it?)
0.05  Sun Dec 2  00:38:00 2009
        - added more tests (now S_3 and S_4 are tested)
        - added some more pod
        - added conjugate elements and conjugacy classes
        - mutliplication method now different in CM::Permutation from CM::Permutation::Cycle
        - added centralizer and center methods for group and elements
0.02  Mon Nov 2  16:43:00 2009
        - added some more tests for permutation and cycle
        - cycle_algorithm now returns cycle objects
        - added order() method for cycle permutation and group::sym classes
