[Paraview] further documentation for extra plugins

[Dan Lussier]

I was wondering if there was a central l location for the  
documentation of plugins that are distributed with ParaView?

I am thinking of those which are automatically bundled along with,  
such as SLAC, Analyze, Prims, etc.

I saw there were some dead links on the ParaView wiki which might  
contain the data but that was about all I could find.

Thanks.
