[Paraview] Send an array from client to server

[Utkarsh Ayachit]

(hit `send` prematurely, ignore previous email)

How big is the array? For 100s of values, I'd say IntVectorProperty is
still reasonable. Any other approach will mean that those values are
not going to get saved in state files and such. For a one off push to
server side for values you don't care to be saved in state files, you
can directly call API using the vtkClientServerStream on the proxy as
follows:

  vtkClientServerStream stream;
  stream << vtkClientServerStream::Invoke
              << VTKOBJECT(proxy)
               << SetValues
               << maxValues;
stream.InsertArray(values, maxValues);
stream << vtkClientServerStream::End;

proxy->GetSession()->ExecuteStream(proxy->GetLocation(), stream);

Assuming a server-side API of `void SetValues(int count, int* values);`.

(please confirm the API, but this is pretty close to what it would look like)
