Found unaccounted for data in iterative alginment algorithm.  The initial rough shift (an index

around the simplfied verts) was not being taken into acount when assesing alignment quality
after propogating the fine grain shift down the curve at each iteration.  Luckily, all low level
code is robust and was behaving as designed.
Initial attempt to refine the feedback to the user when not live updating cuts.  For bigger meshes

this will be crucial to performance and user experience.  Currently just draws the COM and
normal. In not a very good color
