[Paraview] Naming two output ports

[Rafael Küng]

Hi there

Could you please help me: How do you name the output ports, so they show 
up in the pipelinebrowser in paraview?
Example: the ContingencyStatistics filter produces 2 output: 
"Statistical Model" and "Assessed Data".
I can create the two output, but no idea how to name them. looking throu 
the statistics code did not help, as it was very confusing..
