Mesh-mesh intersection done, needs testing
Unit tests for kdtree_from_segs, lookup_adj_segment
Small fixes for make_intersect_polylines, works for simple case
Fix verb.unique and a number of robustness issues in mesh-mesh intersection
More experiments, mesh-mesh intersection looking very solid
First pass on refining two mesh intersection points to underlying NURBS surfaces
Refine surface intersection curve
tests for intersect_tris
Small fix for lookup_adj_segment, unit test
Another surface surface example
Revive a number of AdaptiveRefinementNode tests
Fix tests
More adaptive tessellation tests
Fixed transition patch triangulation of adaptive tessellation
Merge pull request #6 from memononen/master

Fixed transition patch triangulation of adaptive tessellation
Example tweak
Fix merge error
Minor fixes
More experimentation with adaptive tessellation division conditions, dist_to_ray
Use adaptive sampling for surface-surface intersection
