DemoA Help

Probably, not much help is needed for this control panel.  However a few points
are worth mentioning:

   --- many of the demos are randomized, so they are different every time you
       run them

   --- most of the demos, but not all, work in anaglyph stereo mode. 

   --- some demos have their own little help pages.  over time the number that 
       have will increase.   update your KnotPlot frequently.
