Create sample notebook for using Named Tuples

[natashadsilva]

Show how to use when it is the schema for a topology.source() and invoking SPL operators.

This notebook should demonstrate following latest streamsx features:

• nested Named tuples as schema definition
• window Punctuation insertion
• window Punctuation processing in Callables
• usage of submission time parameters
• punctuation based tumbling windows

* window Punctuation insertion

Instead of this, it could have more value to demonstrate how to create a composite source in Python, which generates window puncts.

Hi Rolef, I think the notebook should be kept simpler so we can keep punctuation features in one notebook, and named tuples and nested tuples in another.
I think parameters can also be a separate notebook.

The notebook is a good example for time series, but I am going to leave this open because the notebook is quite complex, covers a lot of features. When we have time we can do one that focuses on the data model.

There are sample notebooks demonstrating NamedTuples:

• Streams-TimeseriesForecast.ipynb
• Streams-QuerySample.ipynb
