Added new pages for Tower Cube 2×2×3, 3×3×4, Cubedron / Cybedron, 6×6×6 V-cube, 7×7×7 V-cube, Dual Circle, Robinson Roulette, and added Gamze Lights Out to the Lights Out page, Arusloky to the Cohan Circle page, Jing Pyraminx to the Pyraminx page, Flowerminx to the Impossiball page Added javascript simulations of Dual Circle, Cubedron / Cybedron, and Robinson Roulette. There is a new Puzzle Statistics page listing the number of positions for all the puzzles, and through plugging the gaps on that page I added God's Algorithm calculation results to the Rubik's Domino, Cohan Circle, Heptalive, Orbik, and Palette Mix 4 pages. And finally I greatly expanded the Cube Subgroups page to include groups generated by middle layer moves and wide moves.

For example Parts 3b and 3c were added to the Mathematics of Lights Out page, a film still was added to the Lights Out page, and the Tantrix page has been expanded.
