[Paraview] Point color according to number of bonds

[David E DeMarle]

You could use a python programmable filter to iterate through the
points and call vtkUnstructuredGrid::GetPointCells() to get the count
of bonds for each one, and store those counts into a scalar array.
Then you could apply the glyph filter and color the glyphed points by
that array.

You might also want to investigate some of the chemdata file formats
that paraview understands and switch to one of those, as those should
do more or less the above internally.
