[Paraview] [Xdmf] Xdmf time series loads as Multi-block Dataset (UNCLASSIFIED)

[Jerry Clarke]

That worked on the ones that I've tried !!
I tried it on spatial and temporal collections of 3DCoRectMesh.

I changed some of the code to try to make parallel reads work
on collections at any level. It works on the examples I tried.
Has anyone tried parallel pvserver on their data ?
