-Since there are no Input validation of the data given for triangulation you need
-to think about this. Poly2Tri does not support repeat points within epsilon.
-
-* If you have a cyclic function that generates random points make sure you don't
-  add the same coordinate twice.
-* If you are given input and aren't sure same point exist twice you need to
-  check for this yourself.
-* Only simple polygons are supported. You may add holes or interior Steiner points
-* Interior holes must not touch other holes, nor touch the polyline boundary
-* Use the library in this order:
-  1. Initialize CDT with a simple polyline (this defines the constrained edges)
-  2. Add holes if necessary (also simple polylines)
-  3. Add Steiner points
-  4. Triangulate
-
-Make sure you understand the preceding notice before posting an issue. If you have
-an issue not covered by the above, include your data-set with the problem.
