[Paraview] pqViewManager in Clone2

[Utkarsh Ayachit]

That's because you haven't registered any readers with the "reader factory".

Look at:
http://www.paraview.org/Wiki/Writing_Custom_Applications#ParaViewReaders:_Reader_Factory_Configuration

You need to specify an XML with the names of the readers that your
applications wants to expose in the build_paraview_client() function
call.
