[Paraview] Custom Python plugin with multiple input ports

[Utkarsh Ayachit]

Sorry for chiming in late, but here are some things to note:

* Both Dennis and Cory are talking about multiple connections on the
same input port. This is arguably not too well supported since the
order cannot be determined easily.
* Seems to me you want multiple input ports, each with a single
connection. That's supported. Just not by the Python Filter Generator
Script. Once you have the XML for the filter, you can indeed just add
another <InputProperty /> tag to it as follows (note the "port_index"
attribute):

<InputProperty command="SetInputConnection"
                         name="Input2"
                         port_index="2">
   <!-- fill with relevant domain information -->
</InputProperty>

Then, your python filter code can access data on each input port as:

input1 = self.GetInputDataObject(0, 0)
input2 = self.GetInputDataObject(1, 0)

Here there's no confusion which data is on which input port.

Hope that helps,
Utkarsh
