[Paraview] access to the filter object from the panel object and vice versa

[Utkarsh Ayachit]

You cannot call a function on  the panel from the reader. ParaView is
designed to work in client-server configurations. In that case the
reader object is located on the server process with the panel is
located on the client and there's no way for the reader to call a
method on the client. If there's some information that you want to
pass from the reader to the panel, we have information_only properties
for that. At opportune times, the panel can call
vtkSMProxy::UpdatePropertyInformation() and have the information_only
properties repopulated by fetching server-side values.

To call a method on the reader from the panel, we have properties for
that. You define a property in XML and then update it from the panel
and call vtkSMPRoxy::UpdateVTKObjects() to push the property value.
