Hello Christian,
a slight improvement would be the comparison of vertex indices, because
the first index in your vertices vector will get vertex_index 0 in the
triangulation, the second will get vertex_index 1 and so on.

Dear readers,
I was so far unsuccessful to find an acceptably efficient solution to
the following problem:
I create a triangulation using
triangulation.create_triangulation(vertices,cells,SubCellData()).
Now I need a mapping between the index of a vertex in the vector
vertices and the dof index.
So far, all I came up with was looping over the vertices and comparing
vertex coordinates, which is prohibitively expensive.
Any suggestions for a more efficient implementation are highly appreciated.
Thanks
Christian
