moved the videos/images out of the main addon directory to speed up my automatic

addon updater which keeps my blender addon directory current with my development directory
eg...it was copying/deleting the videos every time.
added a shift function in the space evenly on loop utility to allow fine grained shifting of the

simplified cross section.

Added ngon support by making a temporary object and triangulating Ngons.  Not the prettiest
solution but it does work.  Until obj.ray_cast returns the appropriate bmesh face index and not the
triangulated face index (which often doesn't exist in the bmesh) this is the most secure solution.
iterative auto alignment creates very nice results sometimes.  Occasional bugs

ability to shift individual rings for fine tuning
fixed small bug in vertex distributiong when shifting along the high res cross section
