Group Tool done

I finished rewriting the Grouping tool. It has multilevel grouping ability. That means you can put groups within groups. The group tool is needed to create 4 other tools I've designed. (Mask tool, Necklace tool, Kaleidoscope tool, String tool). A few days ago I rewrote the Necklace tool, because I found some better code for animating curved lines. I think it will be a week before the necklace tool is complete. I may even make this a separate little website script for my mothers site.
