ADJ2TRI Generates triangulation from adjacency matrix

Usage notes

• Only supports single component meshes
• If the mesh is poorly conditioned - in particular, if there is a triangle of vertices that surround 1 or more vertices (especially near the boundary) - the algorithm implemented here may fail (a lot of the complexities of this code are already trying to correct for this)

Timing

| Vertices | Faces | Time (s) |
| :------: | :---: | :------: |
| 400      | 800   | 0.0416   |
| 3600     | 7200  | 0.3062   |
| 10000    | 20000 | 1.6139   |
| 19200    | 39200 | 6.2472   |
| 32400    | 64800 | 21.0001  |
