What happens if there are more than 6 pairs of points? What if I have 2
images that have been converted to pointsets? Couldn't I input the whole set
of points from the 2 images(fixed and moving).

Also when I try to run the IterativeClosestPoint2.cxx given in the examples
after building it successfully my program crashes. What could be the reason
since I do not get any error messages?

Thanks
Lisa
