Folded model always fits the model (Not only foldline).
Extend functionality of translat, rotate, scale functions to itself to an initial model.
Minor improvement. That finaly finaly make it works.

  - If x or y coordinates of foldind line point are same than add noise (1 pix) into it. Otherwise Vector2D.intersect doesnt work.
  - Change foldLine from line to segment. It works better somehow.
  - Increase offsets of folding lines in the direction of the line.
