Locate which triangle a point is in

[HugoGranstrom]

I have interests in using Delaunay Triangulation for interpolation, but I can't seem to find any functions suitable for that. locatePoint was the one I found, but it just returns the nearest edge (2 out of 3 points). Am I just blind or is this still not implemented? And in such case, how hard would it be to add? 😄
