[vtkusers] Proving a surface mesh of closeness

[Dominik Szczerba]

If it is manifold then pick the 1st element and make sure each one it has the 
proper number of neighbors (for triangles: 3). Mark the element as 'visited' 
and visit all his neighbors, repeating the procedure. At the end, if number 
of visited elements equals to number of elements in the mesh and all have 
their expected neighbors the mesh is closed.
