[Paraview] [Feature request] Expanding PVD File Components

[Olumide]

I don't know what you mean by multiblock dataset, but here's an example 
of how I use PVD files -- to compose multiple files:

<?xml version="1.0"?>
<VTKFile type="Collection" version="0.1" byte_order="LittleEndian">
	<Collection>
		<DataSet timestep="0" file="Data_Patch_0.vtp"/>
		<DataSet timestep="0" file="Data_Patch_1.vtp"/>
		<DataSet timestep="0" file="Data_Patch_2.vtp"/>
	</Collection>
</VTKFile>

It would be nice to be able to expand the PVD file in the pipeline 
browser in order to see its various file components and optionally hide 
some of them. For example, if the view is cluttered, I may wish to 
suppress the display of Data_Patch_1.vtp.
