[vtkusers] Reading points from a file for Delaunay's triangulation

[Pedro Correa Hernandez]

Hi, I have some problems to import a set of 3D points from a file to 
triangulate them. For instance in the file Delaunay3D.tcl, instead of using 
points created randomly I would need to read the points from a file 
containing them (whichever the format).
Here is the file Delaunay3D, with the part of random creation that should be 
replaced.
Thanks

Pedro
