[vtkusers] multiblock time series file writing

[Berk Geveci]

Hi Gerrick,

The time support that is in the single dataset XML writers was never
extended to support multi-block dataset. There are several ways of doing
what you want. The simplest would be to write out a time series (1 vtm file
per time step) and then use a reader that can handle that. Before I get
into more details, what are you trying to accomplish? What will you do with
the time series?
