Edge-Constrained volume smooth (sometimes called ObjectSmooth or QuasiSegmentation in FireVoxel):  implemented a Zero-Edge variant when the thickness of the edges is 0 instead of current 1-voxel.  This allows not to use artificially higher resolution for better result.

Smoothed power=80

This is one of the principal components of the BiCal. But also it has a big potential to improve other operations, possibly MagTrace, and as as the pre-processing for more complex segmentations.
