[vtkusers] Generate triangulation from vertex and index info

[Hugo Valdebenito]

Hi all

With the delaunay2D (3D) schema, the distribution of triangles is not the
same, depending of the input points order. If I already have the vetex and
index definitions for the triangles, how can I make the triangulation?
