[Paraview] create a time sequence from a steady-state vector

[Utkarsh Ayachit]

Using "Programmable Source" or "Prorgammable Filter" may be the best
approach. Chapter 13 in the ParaView Guide covers a great deal of how
programmable filter/source work. Give it a quick read and let me know
if you need any assistance.
