Allow Conduit information to be made available in ParaView Catalyst Python scripts
ParaView Catalyst Python scripts should have a mechanism in order to allow the Python script to access the Conduit information passed through the Catalyst V2 API. This would allow the Python script to access information passed through Conduit for doing programmatic things inside of the Python script. As an example, it may be useful to determine all of the channels available in gridwriter.py
so that the proper channel name can be passed set for the registrationName. Currently the channel name is hard-coded. Another example is being able to change the Python processing pipeline based on information passed through the Catalyst V2 API.
