[Paraview] script for moving a sphere

[Andy Bauer]

You can try creating a sphere source and then use the animation view to set
the z-value property of the sphere to change with time.  The link for more
information on that is at
http://paraview.org/Wiki/ParaView/Users_Guide/Animation.

The following python script is a bit long and has extra stuff in it (like
the cylinder to give it perspective) but hopefully demonstrates this.  I
created this script with ParaView 3.12's python trace but hopefully it
works with your version too.
