I Removes equal points (leave one of equal points) from theWLine and recompute vertex parameters.
II Removes point out of borders in case of non periodic surfaces.
III Removes exceed points using tube criteria: delete 7D point if it lies near to expected lines in 2d and 3d. Each task (2d, 2d, 3d) have its own tolerance and checked separately.
Returns new WLine or null WLine if the number of the points is less than 2.

Joins all WLines from theSlin to one if it is possible and records the result into theSlin again. Lines will be kept to be split if: a) they are separated (has no common points); b) resulted line (after joining) go through seam-edges or surface boundaries.
In addition, if points in theSPnt lies at least in one of the line in theSlin, this point will be deleted.
