So just replace any spaces with a newline and pipe it to the svd script.

meh.  For the time being we can just create/resize all matrices with the
optional appending of ", 0)" like so:

inv_matrix[index].resize(matrix[index].size(), 0);

I'm not sure what the limit is, but I doubt that you or I would be using more
than 500 points just to do some orienting.  I think right now, just keep it
simple, and get a "flow" working so that we can integrate POV-Ray's .ini and
post-render capabilities so that an object can be "scanned", the vectors written
to disk, SVD can spit out an orientation matrix, and the scene can be re-run: at
which point it checks to see if a data file and/or matrix file has been written,
and then it just skips over to the part where it renders the oriented object.

I'll look it over and see what I can hammer out.   Busy day.
Thanks for the tips.   :)

Having fun with our new friend I see  ;)
