Ok, I see.  If that's all this is, maybe it would be better to handle strings as array-based arguments, like the other 
array-based arguments.  I was just hoping to avoid all the double pointer stuff originally.  My concern with starting to 
discuss wrappers is all the other issues that will come up at the same time.

Shape, and secondarily iRel.  I think people have made reasonable progress on iMeshP, except maybe me, and that should 
get fixed soon.
