Hi,

I have generage triangles using Delaunay triangulaition using several
points, and now I have the vertices coorinates of one triangle, and I want
find the index of the triangle in triangles.
Example:
For simplicity, using only four points:

and generate two triangles using the Delaunat_trianglation_3 class:

the first triangle:

the second triangle:


now I have the three points(p0, p1, p3), and want to find the index of this
triangle in the triangles. Is there any efficient method to do so? As you
know, allways there are much more than only four points, so the efficiency
is very important.
