Adjusting # of cuts changes general orientation based on view

[patmo141]

Initial drawing of path creates cut directions based on the path drawn and the view direction.

However, when adjusting the number of cuts in a segement, the segement should redistribute new cuts, attempting to preserve the orientation of the previous cuts. For now, adjusting raw # of cuts should be the first thing changed after drawing a segment. Then segment level operations like segment shift or smoothing applied
Then loop/cut level operations like rotate, shift, translate, individually added cuts

Plan:
Implement better segment based operations utilizing the segment backbone and incorporating shift and alignment information from the cuts in the segment.

Sounds good to me.
