Summary

Add a fit_to_points method to the FFD class that automatically positions the FFD bounding box based on the input points. This provides a more intuitive default case for morphing setups. This is resolves issue #135

Changes

• New method FFD.fit_to_points(points, padding_factor=0.05)
  • Computes the axis‑aligned bounding box of the given points.
  • Adds a configurable padding (default 5% of the object size) ensuring some room for deformations and covering boundary points.
  • Sets box_origin and box_length accordingly.
