- added rcFixupAdjacentContours which adjust adjacent contour sets so that that they share all vertices (still buggy!) - changed the demo stucture to handle tiled navmesh generation process (still ugly) - the performance results are put into a struct instead of logged immediatelly - added ChunkyTriMesh class which allows to partiotion a trimesh to smaller pieces using AABB tree
